HELP NEEDED!!
Ok so having a problem with my truck. 94 f350 powerstroke. When it's cold, it runs great. Tons of power, idles smooth etc. But when it hits operating temp, it throws a check engine light, loses all power and if I don't keep my foot to the floor basically, it dies. I've replaced the IPR, ICP, CPS, new fuel pump, filter, cleaned the screen in the regulator, UVCH 2 months ago. I'm stumped and can't seem to pull any codes. Any ideas ANYBODY?

Loss of oil pressure in HPOP to injectors? Pull plug to make sure it's quarter way from the top after warming up and turned off, next thing I would think is the pick up foot in the fuel tank has rotted with pieces in the tank it it gets sucked up after awhile into the pick up tube causing restriction and when truck is off it falls away. Wouldn't explain the CEL but worth a look.
