Has anyone experienced this? Twice travelling along the 110k freeway my Patrol has kicked quite severely a few times and then the entire system shuts down. I mean everything just dies. It's as though I've switched the car off. Luckily I've had enough momentum to get to the side each time. As soon as I switch the key off, and restart all is hunky dory - as though nothing happened. Is this a safety mechanism for dirty fuel? Or is it maybe the DP Chip or car computer playing up?
