Order of inspection
P0337 Crankshaft Position Sensor A Circuit Low High
The P0337 code means the signal from crankshaft position sensor A is lower than the computer expects. Without that signal there is no spark and no fuel injection, so the engine can be hard to start or can stall while driving. A shorted signal wire or a sensor with no power is the usual reason.
