Default Intermitten Shuts off after starting

Hello all. Looking for help. 2002 C5z06. 80k miles. Will intermittently die right after starting. If i put my foot on the gas pedal, it will fire up, rise RPMs, and stay running / idling. happened maybe 10 times so far. Seems both cold and warm.
It seems like - when it does it, i'll start it back up, give it gas, or just try it a few more times, and the car will eventually fire up and stay idling.

No current codes. Column lock issue was corrected by dealer in the recall back in 2004. Looking for help on where to begin / what to check / what to replace. Thanks.

You need a scanner capable of displaying live engine parameters. Check fuel pressure at the rail with key to ON (not start).....pump should run for 2 seconds.
