1996 7.3 completely stock. 268xxx miles. Leaving work the other day truck died on me seemed like typical CPS problem. I actually had 1 in the truck. I replaced and truck fired up, stumbled a bit for a out 30 sec and then ran fine. Coming to work this morning truck did the same thing. It did seem like it was down on power a bit then felt really strong before it died. It did start back up after a min or 2 and seemed to run fine. I only drove it a short distance as I went home to switch cars. Any help is appreciated. Only difference I can think of is where I bought fuel. Truck has ran perfect before this week.
