lt1 no start when hot lt1- cammed, new injectors, new spark plugs, aftermarket spark plug wires, new starter, new battery.
Car cold starts perfectly fine, runs/drives fine as well. If the car is left running for longer than 20 min and shut off (or stalled) car will not turn on until it cools off for about half an hour.
It will continue to crank, Getting a jump from another car doesnt help. Ive had this car for just over a year and it has always done this.

possibly the ignition coil or the ignitiion module getting heat soaked. Coils can work fine cold then fail hot. We used to test them (warranry returns) with a heat gun at work while they were sparking on a fixture and see if they eventualy fail when they get hot enough.
If it turns out to be the ignition module, we spaced them off the head a little bit with some washers to give them some more cooling
