after car sat awhile, was able to start up and drove for approx 2-3 miles before doing the same but the idling sound increased before stopping. haven't tried to start van up since.
check engine lights came on, headlights flashed off, then car shut down. on 2004 Pontiac Montana
Probably a failing battery or alternator problem. Need to get both tested and replace the faulty one. Odds are its the alternator.
have charging system ck completely incl battery
Most likely your alternator is failing...have shop check for alternator and battery
