Here's the deal... changed the valve cover gasket on Saturday and when i was done the truck started no problem. Get it home (20 min drive), it sits for 30 minutes, still starts fine. Go to work (10 min drive), truck sits for 6.5 hours. When i turned the key, there was a short burst of electricity (lights and stereo come on), then goes out... no juice.
So what's the deal? I've had no problem with the alternator before, but have with the battery... any suggestions?
