Dies while driving not losing fuel pressure or oil pressure. It stutters like a gas motor losing fire then just like somebody shut the key off it dies. I can put it in neutral and it cranks a second and fires right back up. Sometimes I can drive it for miles and sometime just a couple hundred yards. Truck came in for crank no start found bad hpop fixed that and now it's doing this.

 

Check connectors on ficm and all wiring you may have moved for loose connections and chafed wires.

 

IPR valve, when they start going out they randomly die. Had it happen to a dozen pickups come through my shop.
