2015 Yukon shuts off while driving

[Jamiebeaird]

2015 gmc Yukon Denali shuts off and turns back on while driving. It’s completely random.
Happens on bumps and smooth roads, hills and flat ground, 70mph and 5mph, turns and straight. There’s no way to make it repeat itself. Was happening about once a week or so, now it’s every drive, sometimes multiple times in a 20 minute drive.

What happens: truck acts like it shuts off, gauges die, radio and AC cut off, doors unlock then relock and everything goes back to normal. Screen says stabilitrac unavailable and collision avoidance unavailable. But no codes and all this happens in about 1 second.

All grounds have been cleaned or replaced, negative battery cable has been replaced, battery has been replaced. Even checked the G218 ground under the driver side dash. Still no fix.

Any one has similar issues and found a fix?

Redneck engineering here is to turn the vehicle on and start shaking harnesses and lightly tapping connectors until you find one that replicates your issue then break out the multimeter.
