Classic case of sticking bypass valve. Same thing happened to me several
times before I was able to track it down. Basically the valve hangs open
after accelerating and comming to a stop. The engine stalls and then would
restart a few minutes later, sometimes running rough after the restart. It's
definately worth taken a look at.
