Hi,

I have a 2003 GU Patrol 3L Diesel,
About a week ago when I was driving, I turned a corner and accelerated off,
When I was in 4th or 5th gear and was at about 2500 RPM, it seemed to lose pulling power.

I put the clutch in and revved it a bit and it seemed fine, I drove around for a while and all seemed good, but then it happened again.
I didn't notice it again for about another week, when it happened while just accelerating up a road.
I haven't noticed it since.

On all cases I wasn't accelerating hard.

My Patrol has a Dawes valve set to 15 PSI.
The engine was reconditioned about a year and a half ago and had a new fuel pump installed.

Does any one have any idea what could cause this?

Thanks,

Lucas
