answer would depend of type of car and the fuel system setup if it is a multipoint injection system (has multiple injectors instead of one) then the fuel rail is sitting just above the engine which would cause fuel to vaporise when engine is worm and fuel is not flowing (turned off) to combat this the fuel pressure should stay at 1 to 2 bar (14 to 28psi) for at least half an hour after the engine is turned off this is facilitated using a one way valve which is usually situated in the electric fuel pump and can be tested by rigging a pressure gauge to the fuel rail and turning the ignition on to prime it and then off to moniter the pressure drop. if it is an older vehicle with carburettors we used to have a problem with the base of the carb distorting in the heat of a turned off engine (no air flow) which was rectified using a thick rubber base gasket robb

You need to check the crank sensor at the harmonic balancer. when it gets hot, it stalls the engine. let it cool for a few moments then it starts again. If it's hot and stalss and won't start; try spraying water around the balancer, to cool the sensor. Then see if it starts.
