My EX500 died today, could use some advice. TL;DR: Bike won't run or turn over. Starter does nothing, however bike has power, as lights work. No issues noted prior to this. 

So I'm on my way home, and am coming down a large hill. I feel the bike sputter underneath me, however the drive wheel continued to turn the engine over. I attempted to 'bum' start it with the drive wheel, to no success. I didn't accidently hit the kill switch, nor was the bike having any issues prior to this incident. I pulled off to the side of the road, and attempted to start the bike via the electric start. Nothing happened. The starter didn't click or whirr, and the electrical system didn't take a load, as the running lights didn't dim. I could use some advice as to where to start. 

I think it may be a broken kill switch, or the stator.
