Hard starting when hot is most often caused by too much fuel. This can be the result of a float that is not adjusted correctly, or perhaps a leaking diaphragm of some sort.
However, it can also be caused by vapor lock. You should check that the fuel line does not get too hot. Is it positioned near the exhaust at any point?
If you pump the gas pedal before trying to start a warm car, perhaps you should try starting without pumping the gas. Even a little too much gas can cause a warm engine to be too rich.
Good luck.
