Could be the alternator or just a bad ground. If you can, run it up to Autozone or whatever parts chain store is in your area and have them test your charging system. They should do this for free.
Audizine.com and Audiworld.com may have DIY instructions for replacing the alternator.
I had the same thing happen...bad gas cap!
