I need you to try something so we can confirm this. When it doesn't start, have a helper turn the key to the start position while you check for power to the smaller wire on the starter.
You should have 12+ volts at that point. If you do, then the starter needs replaced. If there is no power, replace the starter relay. It's a cheap part and takes about 30 seconds to replace. If that doesn't take care of it, then we need to check the ignition switch itself. Not a fun job.
Let me know what you find.
