My 2008 vulcan engine keeps stalling. What is the problem?

I will be cruising along at 55 or so and it will sputter and die as if it is out of gas, so I switch it to reserve but no dice...still stalls. Even if the tank is full I am experiencing this problem. It will normally start back after coasting in gear for a little while but occasionally I have to pull over and start it up again. Well, the other night I was riding it and I was travelling about 40 MPH, when the engine stalls and then kills. So I pull over and try to crank it, but no go. I had to wait about 10 minutes, and then it cranked and I was able to make it home.
