15 Tahoe won’t shutoff.

[Typhoontom]

My 2015 Tahoe won’t shut off. It has remote start and a start button. Runs and starts fine. I have to pull fuse to fuel pump to kill it. Replaced start button, no joy. Checked all known relays. The same. No obvious wiring damage. Hint. If you hit the stop button all dash lights go off but engine is fine and a/c stays on. And if I don’t disconnect battery, it drains quickly. Bad BCM?
