Sounds like a bad crank position sensor to me. But hey, these cars are full of sensors so check everything down to the temp coolant sensor.

Was having problems with my old LS1 starting when it was warm, turned out to be a bad crank angle sensor.

Alright thanks how did you find out which sensor it was?

Well these cars are relatively simple. Usually boils down to these parts

Ignition relay going bad Cause the car never to start

Crank position sensor can cause the car to die when driving, and cause no start issue

Cam position sensor can cause the car not to start immediately, it usually takes a few tries but the car eventually starts when the crank sensor takes over.

To me it sounds like your car is not calibrating the correct starting temperature for a hot car. It's dumping fuel thinking the vehicle is still cold. I would start with your engine coolant temperature sensor, but it could also be that your intake air temperature sensor is bad or your mass air sensor is going out
