Car wont start HELP!

after the engine heats up (I do live in a hot climate) the car won’t start back up…is fine in the mornings and at night, but not during the day. has a new starter, alternator and battery… what could it be? distributor? another starter? wiring somewhere? I think its electrical of some sort… HELP…no one else has.

When it won’t start is it that the engine does not turn, or the engine turns but does not fire?

when I turn the key, you hear nothing besides the starter turning (I think}…very faint…no clicking at all…
