Same bike I have. Mine did the same thing last August in stop and go traffic in the heat. I pushed it to the side of the road and it started 10 mins later. Never did it again, but I'm guessing it will.

 

I rode for at least 2 hours today with no issues. It was a lot cooler today. After, I made sure all connections and wires to the circuit breaker were clean and secure. I started it up and let it idle for about 5 minutes, then gave it some gas to heat it up, circuit breaker never even got warm. I'll check with the dealer to see if it was replaced. Even if it has, I can replace it again as it's <$10. I hate phantom issues. I've seen comments about replacing it with a 40A Fuse block. Does it really matter?

 

Also, it has a DynoJet Power Vision not Commander, but that's been on it almost since I bought it.
