Do you have any indicator lights on, on the dash? Check engine or anything?
Sorry, I meant when it was running
Basically it sounds like the alternator has stopped charging. The thing is, if the battery won't hold the charge it could also be a problem. What I would do is charge the battery and have it tested. Most parts stores will do this free of charge for you. If the battery tests good, then replace the alternator. I believe from your description the van is running on the battery, which would indicate the alternator has failed.
