Hi there. Most modern engines have both camshaft position sensors (multiple) and crankshaft position sensors. Camshaft position sensors, in conjunction with crankshaft position sensing, allows very precise timing for ignition and fuel injection. When a camshaft position sensor fails, or works sporadically as in your case, engine management shifts to a "degraded timing mode" which is less precise, throws the Check Engine code for the failing cam sensor, but will still run. To have this taken care of, I recommend having a professional, like one from YourMechanic, diagnose the stalling problem and perform the proper repairs.
