This could have several problems. #1 Fuel pressure due freezing water in fuel lines add thermal aid or rubbing alcohol . If you have access to a pressure gauge there is a service fitting on fuel rail that you can test pressure while driving and see if the pressure is gone when car dies this could lead to fuel pump electrical or more restricted lines. #2 intermittent sensor failure Mopar uses 2 sensors to control spark and fuel lose one could lose spark lose the other lose injection with a scanner they call it C/C sync ok (cam/crank) if no then check for each parameters for display.# 3 relay controls ASD and FUEL pump for voltage drops.
