If this helps anyone I had the same issues and replaced sensors n sensors n sensors traced wiring n didn't think it was fuel related because my pump was not even a year old and I had good pressure not running and idling but when I plugged in the datastream and went for a drive I found out under a load the fuel systems would close and I'd either have to stop all the way or turn off the truck n start it again so I ran some tests to narrow it down n found it was a damn faulty fuel pump, that was still under warranty tho ? hope this helps some poor guy save some time n money
