2002 7.3 running rough no power

i was driving my 2002 7.3 ps down the highway about 70 mph today when i lost all power and started running really rough. i to get to the next exit but didnt make it. the engine re started and ran really rough but doesnt have enough power to drive. then i tried to start it again and it wouldnt start at all. all out of nowhere it was fine before. i have no check engine light. what do you guys think? harness? injectors? cam sensor? anything i should check to narrow it down. thanks

joshbmx1210, any update on this. I had the same problem on a 2000 last night on the way home from FL to ATL. intially thought t was water in the fuel, we would pull off, dump the seperator and roll for a few miles then it would happen again. Let truck cool down, thenit would run fine for lmost an hour then act up again... Noted, that there is an old school SuperChips installed since new, no problems until now, 100k later! Please help!

Check oil level. I let mine get a couple of quarts low (not sure why) and the performance dropped off. Topped it off and all seems to be fine now. When was your last oil/filter change?
