Good Afternoon Gentlemen, I am having a problem with my truck, and hopefully someone on here can point me in the right direction.
Strangest thing, truck starts and runs smooth,no problem. After driving on the highway for a while, it just stops. No bucking, just like you turned the key off.
Try to restart....no go. Cranks, but won't fire. Let the truck set for 10 min or so, and fires right up. Sometimes I can go for miles before it does it again, sometimes 20 feet. Obviously has fuel pressure, or it wouldn't start/run. No codes coming up on dash. Pulled off intake manifold, and changed out cam position sensor. Didn't help. Maybe crank position sensor? Anyone have any experience with this? The closest GM dealer is over an hour away.... don't trust it to go that far.
