Update: My friend/mechanic replaced the ground wire cable on right side of engine on front of the head. It goes to wiring harness on engine that goes to the computer box under the hood. Drove over 60 miles no issues. All codes have cleared. I will continue driving if this is not the fix, I will post again. Fixed with $39 ground cable with crimped ends at both ends. DO NOT BUY ANYTHING BUT GM PRODUCT. Save yourself time and headache. PS Just because a wire connector looks good double check. If any connector wires are loose do not recrimp but replace.

I purchased 2008 GMC Sierra 1500 in April. Mileage 51,253. Experience few electrical problems without dying. After turning off, it would not start until moved back post wire around. Thought issue was fixed by tightening positive wires at bottom. Original issue started again last night moved the back posts and restarted. Today, driving 70+ on toll way, door locks, engine lights, radio started going crazy. Tach dropped a couple of times, then lost power twice and both times pulling toward shoulder it regained power. I was able to get home. It would not start again until I wiggled the back post wires again. HELP
