Weird issue with my tahoe

[dp1225]

Hey guys in having a strange issue with my 08 tahoe LT I will start and run perfectly fine but there are times where it just dies all electronics return to factory settings. Volts read fine now drop in voltage. Wondering if its something other than a batt and alternator issue?

I had something similar happen to my 2000 Tahoe and it turned out to be a ground. There are 4-5 places where the electronics are grounded. You will have to google your year. I fixed the ground and it took care if the problem.

I find that when the truck goes dead... Even though I have cleaned and tightened my batt terminals. If I wiggle them the power is restored to the truck. I'm guessing maybe crappy terminals ? Chevy should have never changed the side posts -_-
