During today's morning commute on the freeway my 2015 v650 stalled. I was able to safely pull over. After a few attempts it hesitantly started again and it let ride half mile towards the mechanic shop and then stalled again. It did not start again. All the bars of the fuel guage were flashing when I turn the key to ignition. It had to be towed to nearest dealership while they look at it and I am nervously waiting what could be wrong. There was plenty of gas. About 100 miles ago I had replaced the air filter, I am wondering if i did anything wrong there. Any thoughts?
