OnGoing Electric Issue

[mikemalina]

I have a 2009 GMC Yukon Denali- Every 3-4 weeks the entire electrical system goes wacky. Starts with the check engine light, then the car goes completly dead while driving it as the gauges start flipping out and nobody can seem to figue it out. Last time it happened I tugged on the battery cables under the hood and everything reset and turned back on! The dealer has no answers I need help! Anyone? Please help- 80k miles on it, runs great when everything is working! But dealer keeps charging me 500-600 to look at it! Always something wrong but the problem??? HELP ME IN KANSAS! Thanks GREAT BOARD!

sounds like it could be bad cables and connectors going to the battery. People on the forum here have had that happen before...
