I have a 21 RTL and was just coming back from Sturgis last year. It was hot and when we got to Denver there was stop and go traffic. When I came to a light the bike just shut down. No warning, no codes, it just stopped. I had to push it over to the side of the road and not freak out. I let it sit for a minute or two and then it started right up. The same thing happened a couple of weeks later. Hot day, stop and go traffic and come to a stop light and it just died, no warning and no codes. I let it sit for a minute and it fired right up. I took it to the dealer and the tech thought it might be a smog device so we took it out. No problems until Saturday and it happened again. My question is there some kind of heat sensor that might be causing the problem? I am all out of ideas.
