So I was riding my 88 v-max the other night and suddenly the gas light came on although the tank was almost full. I had just filled it so I thought it was odd but I kept riding. Sure enough, it sputtered and died shortly thereafter. I shined a light in the tank to verify that there was indeed fuel in it. There was. About 20 minutes later, I was able to start it and I rode it home without issues. What could cause this? I'm afraid to ride it outside walking distance from home now.
