So I had this happen last week. Drove to the gas station then home. After sitting for about 20 mins, I go to leave and zero power when I turn the key. No lights, my autometer gages don't light up, wipers don't work. Zero power inside, no clicks, nothing. Then after about 5 to 10 mins, it turns over and starts right up. It's only happened twice now. I did wiggle my keys, replaced the fuse just off the battery... last time that fuse was blown, but it was not fried this time. I wiggled the phone charger in my cigarette lighter outlet, and I also wiggles the keys in the ignition. About 10 seconds later it started up. New battery and alternator in the last month, pulley and fan loosened up and tightened it up, 15 seconds later it was loose and rattling, so it was replaced. What cause all power to just stop, lights, radio... everything and then just start a few minutes uses later?
