Well, there is
an ignition problem
that can cause this when the engine gets hot and it stalls. It’s caused by a lack of spark which can be either the ECU’s fault (on EFI cars), or the coil on pretty much any car. Heat causes expansion. An engine needs more fuel when it’s cold than it does when it’s warm.
