'95 F250 7.3L interminnent power problem

[jorosal]

I have a major problem with my '95 F250 7.3l diesel. All of a sudden lost complete power and idled like it was starving for fuel. Engine light comes on. Engine light went off, everything was fine for the day. I get home and right before parking it the same thing happened. Lost all power, barely stumbled into parking spot. Opened the hood and the driver side valve cover was smoking and smelled like an electrical burn. Replace the valve cover gasket and the internal connection to the glow plug and injector.

She kicks over on the first crank but with the same problem. Stumbles as if starving for fuel with the engine light on. No codes ever come up. (maybe I need a specific scanner?) If I let it idle for 20 minutes, the engine light will go out, idles normally and all powers restored. Drives perfect. Then it will cycle through the same symptoms.

I have changed the oil, fuel filter, cps, fixed the wiring harness where the old valve cover connection had fried and cannot think of what else to do. I am hoping it is just a sensor such as the exhaust back pressure sensor, or the injection pressure sensor. I checked the Fuel Injector Module for water contamination and did not find any.

any suggestions?

My first guess was going to be the UVC harness but you already fixed that so here's a for ya.

when it smokes like that, it's the UVC harness going to the injectors.
