Electronics cutting out while driving

So when I hit a bump or get on the brakes, my radio, AC, dash, Everythig electronic cuts off and on. Tonight even the trans would switch from drive to neutral and back over and over. I pulled over and cut te truck off and restarted and got home fine. Can someone tell me what the hell is going on? Where is the computer connection on this?

Oh, this is our Escalade so basically a suburban.

I would check the battery terminals.

Could also be a ground issue.

Year Escalade? Usually this is a ground issue, the most common being the chassis ground at the battery itself. I would check those and clean your battery terminals.

Exactly what I was going to say. My car was cutting in and out on the dyno because of a loose ground on the back of the cyl head.

Found it! There is a bracket that holds in the battery that had come loose and was leaning against the power cable on the back wall and causing it to ground on the frame.
