What would make a Dodge Caliber quit while going down the road and not turn over?

A Dodge Caliber may quit while driving due to several reasons, including a failing fuel pump, a dead battery, or an issue with the ignition system. Other potential causes include a malfunctioning alternator or problems with the engine's sensors, such as the crankshaft or camshaft position sensors. Additionally, a clogged fuel filter or a severe engine issue could also prevent the vehicle from restarting. Regular maintenance and diagnostics can help identify and prevent these issues.
