I can not hazard a guess without knowing the following - What color is your bike?
Seriously, I'd think that the problem (just a guess) is possibly an electrical open (since fuses are not blowing) and the likely candidates are the hi/lo switch or a faulty (loose) connection. Have you had the front cover off the bike recently?
