Could be that the switch is wearing out internally. I got caught 200 miles from home with a switch that wouldn't quite push far enough to start. My side of the road fix was to wrap a heater hose clamp around the arm that pushes the switch button adding a bit of a shim to press the button further down. Got me home.
