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. The ECU or the coil gets hot and expands.
Why does my car turn off when it’s cold?
The problem occurs when the car is transitioning from cold-start to normal run conditions.

What causes an engine to stall at idle?
Stalling problems trace back to three primary causes: a lack of fuel, not receiving enough air, or insufficient power. Common reasons include an empty gas tank, a faulty fuel pump, a bad ignition coil, fouled spark plugs, water in the fuel, or a failing sensor. An engine stall is never fun.
