Another point for you to consider: I don't remember you mentioning that you changed the check valve on your fuel pump. The fuel pump itself can't cause a hot start problem, but the attached check valve can. On some models they can't be separated, but on others they screw together with a copper crush washer in-between. Keep in mind that the copper crush washers aren't supposed to be reused. Perhaps you have a bad ignition coil that opens when it warms up? But then that would stall the car, too. Walt
