Default 2008 suburban electrical shortage/problem

I have a 2008 chevy sub 1500 4x4 80k miles and it is having electrical issues. I will be driving down the road and randomly the service 4x4, park assist, abs and traction control sensors will go off. My ac will also shut off and a couple times my door locks have gone off. I will also lose power to my dash gages. Most of the time it will go off and then rt back on. I notice it does it when my ac is on high! Please help

I'd start cleaning Grounds. Take apart, brush to bright (contact area and terminal) and replace.
Just anywhere you find one, clean it good.

I have tried that with no luck. I think it has something to do with my ac any ideas?

Its a shot in the dark, but might want to have the battery and alternator tested.. could be things crapping out when under load...
Check the connections at the alternator as well... if your battery is more then 3 years old I would for sure have it checked out...
Every time I have had some odd anomaly happen the root seems to always be the battery.. I think I am on number 4 now...

Good idea !, but I'm still thinking a connection issue.
Loose relay, terminal, something like that.
