So funny you should post this as the same thing was happening to me. I would have that same issue, happen every now and then. Maybe once out of every 15-20 starts. It then settled down and was no longer an issue. Than, two weekends ago, I was about 30-miles from my home, riding my bike. I wanted to stop and take a picture as I was on a nice, deserted back road, but the road was on an incline, so I turned off my bike so I can leave it in gear so it wouldn't roll back. I took my picture, went back to the bike, turned the key, and... nothing. Not a light, not a click, just nothing.
Fortunately, a dude on another bike happened to be riding down the road about 10-minutes after I had the seat out and was trying to get power to my bike. He tried to help, but was as baffled as I was. He was great though and went home and brought his van and trailer and got me home (I made him take $100 for his troubles since it was a bit of a drive).
I tried to jump the bike off of my truck, but still nothing, so I feared there was something else wrong with the bike. I am not good at tracking down electrical issues, and this bike has so man electronics, so I just decided to have a shop look at it. I took it to a shop about a mile from my home that I trust. Ultimately, they tested the battery and I had a bad cell. It was weird I wouldn't even get any lights or anything, but they replaced the battery. Also, he found that the connection from the key switch was also really dirty with a bad connection that they took that out and cleaned it up. Now, the bike fires up, I get electrical to everything, and I am a happy camper.
Anyhow, didn't want to steal your thread with my issues, but thought I would just add my experience in case this happens to someone else and it goes beyond the battery.
