My poor GU Y61

Do you have Scangauge? I think its time to get one, great tool to observe what ECU does with all its sensors etc. incl reading/clearing any diagnostic codes.
When engine cuts out do you have to turn the key off and on again (cycle) to get it going again? Or do you just turn the key to crank position from ignition ON position right away?

The reality is, its not as easy as people think, if there is nothing to chase, where do you start. If it is an electrical fault, you could spend hours and hours searching for something that you don't even have a electrical fault to chase.

I do agree, the rail is almost never a problem. Pumps don't generally fail, but we consistently had valve faults on fuel pumps (hino trucks(scv valve)) that would cause stalling, sometimes and other times would run fine. But i am not familiar with gu pumps.

The more electrical components, the harder, longer and more expensive faults are to find, its the unfortunate reality of the modern era.

Rudy,

I thought I had heard of a similar problem before so I did a little checking for you.

Take a look at this thread and it may be of help

The really sad reality is that mostly service tech people have no fcuking clue how the modern automotive systems work and what happens when things don't work. Systems are getting way too complex for the types who leave year 10 and have trouble understanding basic math. These are the people who are recommended by their school career advisors to consider a trade as future employment prospect. It might work for brickies, plumbers and carpenters but certainly not automotive technicians. Logical reasoning, thinking outside the square and understanding basic concepts of physics are prerequisites for that trade.
Any chit kicker can change oil or tighten the wheel nut.
I observe this on daily occurrence how ignorant and incompetent and damn right clueless some technicians are while desperately clutching straws trying to get the computer to tell em where the problem is or what to do. It is hillarous, I'm so glad I don't have to pay for that workmanship in a sense I do but that's another story.
Anyway rant over....

I do a lot of work for the DSE here in Vic. They had at every site all these Patrols parked up and with lock out tags on the steering wheels due to this same problem. They told me a story of one worker towing a fully loaded trailer, he approached an intersection and the car just cut out and he went straight through the intersection and took out another car on the way through.
While this was no help there definately is an issue that Nissan know of as the DSE have maybe around 100 or so of these vehicles and none are being used.

When the engine cuts out been auto I drop it into neutral and then turn it back on from the ON position as soon as I can and as safe as I can not to cause an accident.

That interesting that Nissan know that there is an issue there. Yesterday I rang up Nissan dealer and asked for a goodwill claim thinking that they might meet me half way, but that came back as denied. So I told them that I be will picking up my truck today, which I did and they hit me with a bill of $491.55 for not fixing my truck. I would love to have a business that even though you can't fix what's wrong you can still charge like a wounded bull. Win win business never have a bad day ever again.

Last I heard about this from the DSE Nissan weren't talking responsibility about it too.

You could have a look at the link posted earlier in regards to brake switch although that fault seem to only put engine to idle not actually stalling the engine as is my understanding in your case. Switch should be mounted near above brake pedal it works like mechanical device where pedal/linkage will press on it when released basically momentary push to break/connect circuit switch.
Is this occurring all the times or just at some conditions that is engine cold/hot, long drive than coming to stop, hot day cold day, particular electric/electronic equipment used, fuel tank half full, etc.
You can do a little test, if it is fairly predictable when engine cuts out/shuts down/stalls on coasting to traffic lights at particular speed, particular operating temps etc. Being auto box can you start proactively coasting with the auto lever put in neutral first before you come to stop, let say observe at what speed the engine dies and that try to put automatic tranny in neutral manually and than see if engine stalls again. If it doesn't than I suggest you could have a problem with automatic transmission perhaps its a long shot but it could be that torque converter is not disengaging under some circumstances and once the engine is stalled oil pressure in tranny is also lost so converter free up (this could be lock up clutch in the torque converter).
I'd start taking/observing exactly under what circumstances does this occur like speed, temps, gear selector position (D), terrain etc.

Ok this has been happening for so time so I can answer most of those questions now. This occurs all the time, for example this arvo I it up from the dealership it was sitting outside. I got in and started it and by the time I had reached around and grabbed my seat belt and click it in, the truck stopped. On the way home from the dealership come to the set of lights still idling, the lights to green I go to apply the accelerator the engine shuts down with loads of cars sitting behind me, do the same thing neutral then restart and off I go again. Get home without another shut down. Other times after driving for an hour come to set of lights after exiting the highway and under brakes into the lights the thing would shutdown. In the mornings be it raining, winter or summer I normally leave home at about 3:30 am, and I have a few roundabouts before I get onto the highway to head to work. Most times not all the time coasting into the roundabout just before I use the accelerator it shuts down, making interesting turning without power steering, lucky not much traffic that time of the day. Fuel tanks full, MT sub half full main. Can't say that its predictable though. There was a time I was at the lights waiting as we all do on red, and it shut down and I didn't even realize until the green light came on and I had nothing on the gogo pedal.
