Re: Battery suddenly discharging on '99 XLE
How old is your battery? It sounds like you should do a load test on it to see what the state of the battery is.
How long did you drive the van after the battery was jump started?
I checked youtube and there was a post about fixing a battery by using epsom salts. You may want to try that. Do you have access to a trickle charger to charge the battery slowly as well?
