About 6 weeks ago, I was riding my bike to work. As I was coming into an exit lane the bike engine died. I couldn't get it to start again and had it towed to a bike shop. They cleaned the kill switch and said it was fixed. After a 6 week break, because of back surgery, I tried riding the bike to work again. The same thing started happening. I rode about a mile and a half and it died. Got it started, rode less than a quarter mile and it died again. This happened several more times until I was able to safely park it. About 9 hours later, I came to retreive the bike, which started just fine. I rode it approximately a mile and a half and it died again. The bike engine is turning over but it seems like it is getting no fuel. I have a full tank of gas in it. Any troubleshooting suggestions would be greatly appreciated. I'm going now to try and get the bike started long enough to get it back to my house. Thank you in advance for any help you can give me.
