Very common in a situation like yours for the starter motor carbon bushes to be low and weak for a hot start .
when hot the connection of the carbon bushes to the stator lose contact and cause a nor crank.
To check this you will need a 12volt test light . hook to the "S" wire ( White/pink) on the starter motor .
this is the smaller of the wires on the starter .turn key to start position and if the test light lights up replace the starter motor.
If does not light up check the starter relay .
( out of ten starter is your problem.)
