what do they want to replace and what kind of codes where there... the ignition switch is a common failure, doesnt usually cause a dieout though. I have also seen coils cause a stall concern... typically to isolate that you buy one new coil and swap it from cylinder to cylinder till it doesnt stall any more (hopefully
). low transmission fluid can cause a stall concern. Crappy spark plugs can cause a dieout in chrysler products (if they were just replaced with crappy gimick aftermarket plugs start with OE plugs.
