The backfiring has me concerned, but if it's only doing that as a result of the stalling, and not while you're driving, what has probably happened is the idle speed is too low. It is real common for car batteries to go dead while the vehicle sits on a used car lot. That can happen in as little as three weeks. When that happens, or when you disconnect the battery, the Engine Computer loses its memory. It has to relearn "minimum throttle" before it will know when to be in control of idle speed. Until that occurs, hard starting and stalling can be expected unless you hold the accelerator pedal down 1/4". On Chrysler products meeting the conditions for the relearn to take place is pretty easy. Drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals.
