It really sounds like your not charging. It will run off the battery for a while until it drains the juice. That is why when you turn on any electrical there isn't enough juice to continue running. Check all the connections at the alternator and battery and make sure there is still a belt and it is tight. I would almost bet it is a bad connection or you are wrong about the alternator being good.
