Did you have the old starter tested? Some of the national brand automotive stores will test the starter for you. Battery has a full charge and connections clean and tight? Did you try cranking in neutral, when problem occurs? Do you have any security lites flashing or anything?

You could use a remote starter button, that connects to starter solenoid. Make sure tranny is in park or neutral and a functional e-brake is set. If the tool is hooked up correctly and you hit the button, it should crank. As long as battery--voltage and grounds are good. You have to test when problem is ongoing.

there are no lights flashing for the security system the connections on the battery are tight and clean.
