Car keeps stalling out enough to make the car un-drivable.
Depending on the engine you have would make a difference in the diagnosis I would have. This van may have one of 6 engines to include a diesel one. If it is a gas engine then I would say you are having an issue with the EGR system or the idle control valve. I would recommend you have a qualified mechanic scan your truck and diagnose the stalling for you.
