Another day in Ohio heading to work 20 miles away with no problem... Waiting with truck running in parking lot and roughly at 36 minutes and some change the truck shut off... Finished day truck started, made it back home , left truck running and shut off 7 minutes later... I agree that I need to address the "hack" wiring job & once our supposed snow day Tuesday is finished I'll get it done as you stated and re-install the black ignition contact unit... Keep you posted, I owe you a cup of coffee!Everything I've recommended in this thread assumes the truck is in an "as built" condition electrically. You've now uncovered a "hack job" that cut into the wires that would directly cause this bad behavior. You absolutely need to get into that mess and restore the original connections, with solder, shrink tubing, properly bundled - this is a major reliability issue - quality counts. And yes, this could have effected the BCM, but lets be optimists at this point. Putting the old ignition module might help you since I don't think it was bad at this point (I think the wiring was the root cause), and that would bring in the old resistance value that the BMC looks for in validating the PASSLOCK starting sequence. I wouldn't try the relearn process until the wiring is straightened out.
