Out for a spin the other day. Stopped for lunch and when I restarted it as soon as I touched the throttle it shut off like turning the key. Restarted and the same thing. Third try it ran and we got out on the road. Shifted into second and I could feel it die. let off and it ran. touch the throttle and felt it die. It repeated this several times and since I was going down hill it finally kept going. Ran fine the rest of the day. I have experienced this a couple times at a red light before. I don't know where to start with this one. Thanks in advance for any help.
