    Disconnect the low oil sending unit wire and see if it starts. Sometimes the low oil sensor goes bad sending a false low oil signal. Killing the spark.

    Also, if it is an ultra check under the plastics. In the front there is a small fuse. If this blows then the machine will not start.

    Pull back the spark plug coveron the plug wire back and lay it on the block of the motor and see if you are getting spark from the magnito or as bj22 said, check if the safety switch is not working correctly for starters. I'm not sure but do the Honda motors that are on the PG's have the circuit breaker on them for the low oil indicator? i know on my spray tanks they had them at one time and would trip from time to time.

    I had a Honda motor on one of my spray rigs that would die at random and would sometimes start back up, other times not. When it happened I would drive back to the shop and it would start. I checked the oil, it was full. Disconnected the oil alert, still wouldn't start. Checked the spark plug, functional. It wasn't until I stood back and let someone else try to start it that I saw that the spark of the plug wire grounding out on the valve cover. It seems a small hole had worn in the wire, a little electrical tape and I've yet to have another problem.

    I know what you mean, lol, have had a similar problem before! Luckily as we were trying to start the motor early in the morning and the garage was still abit dim, the arc from the plug being grounded by a bare wire showed up really easy. I know too, that INSIDE the plug wire, there was a fuse where it makes contact with the plug. was never used to seeing that either.

    There's actually two switches. There's one on the handlebars and the other one is on the front of the engine, out of sight. Make sure that one is "on" too.
