intermittent miss/stall/dies

ok so my truck has been randomly stalling/missing/running like crap. It usually happens when i go over bumps (big ones) also when the truck is under load (going up steep hills) then letting off the pedal. On the highway it will drop like 200-300 rpms when i hit a bump almost like its losing fuel pressure.

Ive already replaced the ICP, cleaned the IPR, changed the CPS twice, and put in a reman IDM (I thought it could be electrical). None of these have helped. The truck isn't and hasn't thrown any codes no CEL or SES light either. So now I am leaning towards a fuel issue. My question is where do I start? Are there any relays or electrical connections that could be rattling loose when I hit the bumps? Ive checked the UVCH and that seems fine. I guess what I'm asking is where do I start? is it a pick up line issue? bad fuel pump? Bad injector?

This problem is getting annoying and I need it to be fixed, any help or suggestions are much appreciated. Thanks in advance guys.

I personally have no experience with this but i know one member had absolute fits with his truck doing simalar things as yours and his ended up being the fuseable links right by the power distribution box in the engine bay. Otherwise search "Diagnosing a 7.3 no start" and i have a thread that states everything needed for a 7.3 to run it may help you figure out your problem as well
