Sounds like a sticking Intake valve.. Pull the valve cover to confirm valves are actually closing..

Do you have new spark plugs?
I also fought one with a similar issue that turned out to be bad coils. However, it would run well sometimes and then die completely other times.

Maybe running on one cylinder?

I have to agree with the sticking intake valve. did you notice any screws missing inside the air-cleaner or holding the choke plate to the shaft. These have a habit of getting stuck in the valves. I'm working on a Briggs twin right now where this happened. Usually pull the head and take the screw out from under the valve and reassemble. Can be under either valve. About 40 minutes and your back on the road again.
