If it was hot and you are not maintaining the required pressure in the fuel rail the gas in there vaporizes more easily while it sat and can cause a vapor lock of sorts. There is a pressure regulator in the rail that controls that. A leaky injector or poor fuel pump pressure would do the same thing. That is, if it is a fuel related problem.
