Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Has the wiring to the CKP sensor been checked?
Has a replacement CKP sensor been tried?
Has the tone ring the sensor reads from been checked?
The engine needs camshaft sensor to start but not to stay running.
Test the CKP sensor on the gearbox for a square wave on the White/Blue wire while cranking. Look for the battery voltage on the Yellow/Blue wire and sensor ground on the Black/Slate wire. Look for a pulsed signal on the cam sensor pin 2 Blue/Green wire while cranking. Check for 12 volts reference voltage on the Yellow/Green wire. Test sensor ground on the Black/Slate wire.
Let me know these results.
