If your car had been doing fine, and this problem "just started to appear," then I would bet it's either a sticking solenoid or a sticking ignition switch. When I was having a similar (but different) problem I diagnosed it by disconnecting the starter from the solenoid and then putting 12v lights on the solenoid on both the 12v "in" from the ignition switch and the 12v "out" where you disconnected the starter. Then watch those two lights while you pretend to start the car by pretend cranking (obviously the car won't crank because you disconnected the wire going to the starter). That will test your ignition switch and solenoid. Both lights should light nicely while you are pretend cranking, and both should go instantly out when you let go of the key. If both lights stay on then your ignition switch is sticking. If one light stays on then your solenoid is sticking.
