If I had to guess, I would say there is a ground issue of everything is working properly now. Make sure the battery terminals are clean and tight, the ground to the engine block is clean and tight.
It could be an alternator going bad. What you may want to do is take it to a nationally recognized parts store and have them check both the battery and the alternator. Most do it for free. My only other thought is the fuseable link to the alt may be going bad.
Have that checked and let me know what you find.
