II have a 2005 vulcan with 60,000 miles. About 3 weeks after buying I was on the road driving and the car just shot off on me. Just like that no noises or anything. I pulled to the side put it in park and it started right up. a couple weeks later which would be yesterday i was making a left turn and again it just shut off. Both times were like if you were driving and you turn the car off with the key. Again i pulled over put it in park and it started up. what could this be???
