Fuel issues. After driving for a while

I have a 94.5 F250 7.3. I have replaced the following. Pump, fuel filter, fuel bowl pressure sensor, fuel regulator sensor, IDM, injectors, starter. Now I know two of these have nothing to do with the problem. Like I said truck starts up fine drives fine for a while then all of a sudden start losing fuel pressure, and either it shuts off or I save it. Now the fuel selector switch was stolen off my dash could this be an issue could it not know which tank to pull from??? I am at a complete loss.

Re: Fuel issues. After driving for a while

Thought I answered last night, but don't see the reply. My 95 acted exactly the same, would just intermittently act as if it lost fuel pressure and sputter or die. Wound up being the black pickup tube that attaches to the fuel sending unit. Took out the fuel sending unit from the top of the tank and noticed the pickup tube was not even attached. Sending unit only goes a little further than halfway to bottom of tank. Pickup tube is about 6 inches long and when attached, goes all the way to bottom of tank. I put my phone inside the hole in tank and saw hundreds of little black plastic pieces of plastic that used to be the pickup tube, along with screen. Since sending unit was only picking up fuel from top half of tank, it would act like it was out of fuel from time to time while I was driving. Hope this helps.
