I would definitely check the fuel pressure, should be 41-47 psi. Also, while you are checking pressure, check the bleed-down rate. It should hold pressure for at least 30 minutes or so. It sure sounds to me like a leaking injector or a bad temp. sensor. You could put it on a scanner to see what the ecm thinks the engine temp is when hot compared to when cold. A simple test would be to hold the gas pedal to the floor when you try to start it hot that will shut down the injector pulse and clear a flood if it is flooded.
