The one thing you did not mention is if you checked the alternator WHEN THIS PROBLEM WAS HAPPENING? Bringing the car in for the alternator check when you already got past it will not confirm anything. It may need a new alternator but first check for corrosion at the battery terminals. On GM cars you have to remove the retaining bolt from the terminal and slip off the vinyl terminal covers.
