Intermittent issues are a pain, you have to test when problem is ongoing. Below is a starter wiring diagram. When it refuses to crank, check purple wire at starter solenoid for voltage, key in the crank position.
You can use a starter button to see if starter will crank, there could be safety issues. Make sure the tranny is in park or neutral and the e-brake is set. If neutral, block the wheels, also. Maybe the leads on the starter button are long enough to get you out from under the vehicle. The leads aren't very long. Using starter button to crank starter, no need to use the key. Safety is your responsibility.
