During the time period that is doesn't restart (till it cools off) have you checked to see if there is spark and fuel to the engine? Also, you mentioned you smelled fuel the hotter it got. Check the catalytic converter and see if it is red hot when it is running and warms up. You may have a plugged converter. Also, you replaced the fuel injectors. Did you replace the regulator too? Have you confirmed fuel pump pressure is within the manufacturer's specs when the engine doesn't run? If there is too much pressure, it could be flooding the engine. Also, if the diaphram is bad in the regulator, it could be sucking fuel back and into the intake thus flooding the engine.
Let me know.
