Truck killing issues, need help.

[RES86]

Posted this elsewhere, but here it is for all on this site:

2001 F350 4x4 7.3L, 223K miles

I have researched this issue for about three months now and have yet to find the fix. So here is the issue in a nutshell:

Truck will kill every single time I drive thru one particular intersection. In addition, it has done the same thing in about a half dozen other places. One time it actually would sit and run for me while I wiggled wires and such. I was able to restart it every time but most of the time it sounded like it was firing on one bank. I was able to unplug the ICP sensor and everything would work. This sensor was replaced three days prior to the issue starting. I have since replaced the the IPR and CPS as well. Had it plugged in while it happened and no codes were ever thrown.

There is more to the story, ask any questions you need and I should be able to answer. This is all very intermittent, three times a day to 500 miles apart. Please help, I have seen very similar issues on many forums and never did any of them come to a resolution. Some have even sold their trucks, I can not afford to be rid of this truck.

try replacing your cam position sensor, just replaced mine after the same symptoms. runs like new now.

not saying that's for sure the cause but it's a good place to start, and a cheap, easy fix

I have already done that. I first posted this thread on FTE, I'll post the link here so everyone can get caught up.

Anyone at all?

just throwing it out there but what about the valve cover harnesses? i've read similar posts to yours and people suggesting the valve cover harnesses being loose or something along those lines...

had similar symptoms with 97 f-350 ps. finally isolated my problem to the exhaust back pressure sensor. replaced that and now it runs strong and true.

I have replaced the DS UVCH already. Those wires were visibly in need of repair, haven't got to the PS yet, but they look good outside the VC so far. As for the EBPV, that I have had disconnected for around 3 years.
