2001 f350 7.3 PCM ? Wiring? Nobody knows

So I have been dealing with this for a while and nobody including Ford knows or has ever heard of this issue or symptom and cant diagnose if it doesn't happen while in the shop. I am at a loss of what to do , HELP any ideas or if another Ford owner has ever had this happen please reply. SYMPTOM ; Seems to happen after driving for a couple hours and especially when pulling travel trailer or a load, driving along and running fine all of a sudden no power or pedal, while coasting put into neutral engine still running , rev engine back into drive and goes again, will keep doing this randomly for as long as keep driving and after sitting overnight then does it all over again. Doesn't seem to do it while only driving locally an hour or less. I have had the accelerator pedal replaced, the cam sensor replaced, and couple years ago an injector and the injector module replaced.
Diesel mechanic thinks it is the PCM , cant find one anywhere due to rare California emissions and was going to send to SIA Electronics to rebuild but after talking to tech he didn't think it was PCM ECM problem, said try reprogramming PCM or checking wiring under valve covers, talked to another mechanic says could be wire chaffing probably not reprogramming but very expensive to start chasing wires , said to drive till it gets really bad or leaves me stranded then bring it in ?!!

I Have searched the internet and talked with a lot of people regarding this and no body has ever heard of this which i cant believe another 2001 F350 7.3 diesel 4X4 truck owner or mechanic / tech has never heard of this before or they are totally baffled ! Anyone ?
