Have a weird issue with a Vortec 8.1. Intermittent Reduced Engine Power code. Anyone have experience with this?

Done a lot of troubleshooting and I'm down to either a software issue or wiring. It only happens after shutting the engine down and letting it sit for a bit. Not a hot start issue

typical issue is bad or loose ground wires to ecu, add a jumper with alligator clips at both end and do another ground to the ecu body
