If it is a late model Chrysler, they have been having a problem with their ignition switches. Other than that, check the terminals on your battery for a loose connection, especially the ground.

If either of the above-mentioned are not the case, it sounds as though it needs a trip to the garage. Sorry I can't be of more help, but there is a process of elimination that needs to be done, in order to find the specific cause of the problem. Maybe someone else can give you some other ideas.

Does it stall when you turn other electrical things on (headlights, etc)? If not, I would suggest it is a short in the heater fan motor which robs the electrical system of required amperage. (But.... you would think that would blow a fuse)???
