96 7.3 shutting down one bank?

[82F100SWB]

I got a call from a friend of mine today, wanted me to check out his truck, he thought he might have a sticking injector or something along that line, had a miss and no power, he had been able to make it go away by holding it on the mat, then it'd be fine for a week or maybe a couple days, but, yesterday it started doing it and wouldn't clear up.

I'm a bit rusty with 7.3's(been 4 years since I've had one,) so here's what I did.
We fired the truck up, was cold, hadn't run in a day, ran fine for about 5 minutes, no CEL, and no codes. After about 5 minutes of running, the entire pass side dropped out(verified by unplugging the VC connectors.) The CEL did come on, but, it never did throw any codes.
I checked the harness and all the connectors, found nothing out of order. I didn't have my meter with me, so I didn't check for signal to the injectors or test any sensors.
He has another 96 truck(5 speed though) so, I tried swapping the IDM for a known good one, no change.
Where should I go from here?

just to clearify you pulled the calve cover and checked the connections on the inside cause it sure sounds like valve cover harness has a burnt connection

I lost an inside wire harness on mine on the driver side the back connector took out the whole bank I had to replace the VC gasket and the one inner harness because of how it arc over and burnt up the connector. Lets say that a 65 mph and 15lbs of boost on a 40 mile drive can eat some fuel up. But I do believe it may have something to do with the inside wire harness.
