Welcome to Allpar. The cam and crank sensor do share powers and grounds. If these become intermittent, the PCM can fault one sensor or the other. Either sensor is on the list of 'possible causes' for the other.
The connectors can also become intermittent and throw the sensor fault code, when the sensor itself isn't the actual problem. Sometimes a gentle, slight 'pinch' to the connector terminals will restore a good, secure connection. Wiring harness issues like insulation rub-through to ground and corrosion/bad connections are also possible.
What is the actual 'P' code that the scan tool is showing? You will need to diagnose the problem by eliminating the items on the 'possible causes' list one-by-one until you find the culprit.
OEM parts are important and it could possibly be the crank sensor and either sensor may cause a stall. Low or rough idle may be a dirty throttle body bore and blade from carbon build-up or an intermittent TPS (throttle position sensor) which may not set a fault code.
See if you can read up on the Neon EFI system. A service manual or information on Google will help you understand the system better and help you diagnose the real problem here.
If the PCM has set a cam sensor code twice or more, then you should start with that circuit.
