the push in is the choke or primer so you should only have to use that for either cold starts or lengthy periods of time between using the motor during the day (over 3 hours or more sitting time)
As for the intermittent issue, I had that on my old Yamaha 90hp as well. Would be fine for a while, then at times it wouldn't do anything. I believe it may not be your switch, but a sensor solenoid that will only allow the motor to start when in neutral. If that sensor is going bad, (given it has one) that could be the reason your motor will not start. I bet if you run into that issue again, take the cover off and start it by rope, it will start immediately. That is what I had to do with my old yamaha.
For me that was a very weird issue as well. Bothered the heck out of me, and it would come and go with no predictable pattern.
