Need more info. Does the vehicle starts fine when the engine is cold? Does the problem only happens after the vehicle was driven then turned OFF for a few minutes or hours while the engine is still hot and then the starter would not work?

Do this when the vehicle won't start. Set the Emergency Brake ON. Turn the Ignition Switch to ON position and then put the Transmission in Neutral and then try to start the engine to see if it works.

You can further isolate the starter from the starter solenoid. Most starter solenoid sits on top of the starter itself and some starter solenoid is remotely hidden and located in the engine bay. Get yourself a Remote Starter. It is available at your local autoparts. Just connect one end of the wire to the battery positive terminal and the other end to the starter (it will come with instructions). All you have to do is push the button (supplying power to the starter) and the starter should turn over if the starter is fine. You can now proceed and check the starter solenoid. Most starter solenoid when they heat up they are not able to function properly and fail to provide power relay to the starter. Also make sure you re-tighten all the starter wires, battery wires, ground wires.
