I Have a 2003 Vulcan 800B that I just purchased, After about 300 miles of driving, it just died going down the highway, I waited a few minutes, choked and it fired up. Drove about 2 miles and it did the same thing. I waited again choked it and got home, about 5 more miles. Anyone have any ideas. other than this, it's always started and ran great. It was dry out, but about 90 degrees outside.
