Once warm gauge cluster and door locks go crazy, engine bucks and loses power.

What is your question?

Engine light, reduced engine power and stabilitrack lighs come on. Let it sit and cool down everything is back to normal. I put in new battery and 2gauge ground wire to try and fix issue.

What makes this problem better or worse?

Worse after driving about 20 min

How long has your 2010 Chevrolet Tahoe had this problem?

Few weeks
