Bad ecm (engine control module) or prom chip issue. Prom is located inside ecm QDM is quad driver module which is electronic portion of ecm. Would replace ecm first remebering that prom chip must be swapped from old box to new.

there are several reasons why the remote start won't work, and one of them is the presence of a check engine light. Normally a check engine light comes on when a trouble code is present and recorded by the engine control module. Resetting or erasing the codes can only bring temporary relief, like what u said the remote start worked again. But the trouble will still come back until the real cause is being addressed. You got code on the cam sensor, but car runs fine. Its because the engine computer senses inconsistencies while trying to improve the Emissions system of your vehicle. That we cannot see or hear. Most probably your cam sensor or the wirings are getting intermittent. Better have it visually inspected and replaced if necessary.
