i went up to a store on friday with my moms 99 vulcan, in the parkinglot, when i stated it up, i had the radio blasting, look at my gauges, and the check engine light and batt lights are on, so i started it up again, went to 1300rpm, then to 700 sputtered and died, tried again and it started and that was that. hasnt done it since, it has 54500mi on it and the warranty goes out soon
