serious help needed please

I have a 2002 F350 7.3 and have a problem with it. It keeps making the "CPS" failure symptoms. It dies when running and won't start for a while (10 - 30 minutes) and then it runs again but dies again. I have changed the CPS sensor 5 times in the past 4 days and it keeps doing the same thing. I have no CEL and I hooked up the scanner and reads nothing and there are no codes saved in the memory either. I tried another PCM and that did not fix the problem. I am running out of ideas here. Any help would be greatly appreciated.

I'm not sure if it's the crank position sensor or cam position sensor that's the recall. But whatever you've replaced, could be the other one too?

What kind of scanner are you using? Are you watching the data stream when it dies?

just cause it acts like a sensor check your wiring going to the sensor a rubbed through wire going to ground or a damaged one will also give you this problem

Yes, done that and still the problem persists.

Could be the fuel system.
