I've been having a problem for a while now. Once the truck warms up it will die if its idleing. And it is a pain to restart. If I walk away from it for 15 minutes itll fire right up again. I've checked fuel pressure and I'm about 34psi at the cold start injector. After it died checked for spark and it is very erratic. I wiggled the wiring harness under the intake while it was running and the idle would increase and decrease and would sputter and clear out. I pulled the intake off expecting to find something. But everything looks fine.

Has anyone else ran into something like this?
