Does your fuel tap have a reserve? When I had a similar problem last year, pulling the reserve solved it. Turned out there was a partial blockage in the main tap stand pipe that reduced its diameter but didn't fully stop the flow and the engine was using more fuel than the tap could deliver. Taking the top of the carb off when this happened showed an empty float bowl but turning the fuel on produced a flow.
