I think that it could be the ignition. Maybe the coil(s) if you have them. They sometimes fail when hot and won't fire until cooled down. Try spraying starting fluid in the intake. If it does not fire - bad ignition system. If it fires - bad fuel delivery.

There's only 1 ignition coil on an LT1 motor. But before you go replacing parts, a big question is if you got a tune for your car after you rebuilt the engine.

Alright. Can you hear the fuel pump spool up when you turn the key on with engine off? Should be a whirring sound from the back of the car.
