Same thing happened this weekend on mine-as long as I held it at 1000 rpm It would stay running-after i went around 100 miles non stop it was fine-got home & it's been fine since.It would make sense to clean the idle air control passage as I have 27,000 miles.Once this weekend before it died it would idle at 1500 and not come down-no check engine light or battery cables loose-gonna check the IAC tomarrow-lot's of rain today.

 

I had some idle problems also, But I'm using a ThunderMax ECM. Mine wouldn't idle down though...like a cable was stuck. I called them (ThunderMax) and told them the problems I was having. He told me he wouldn't even talk to me until I changed the fuel filter( which was supposed to changed at 20k anyhow). I went ahead and changed the filter and the other lines inside the tank. It was like riding a different bike. I called him back....and thanked him. If you got around 20k miles on your bike, in won't hurt too bad to change the filter.
