Since your filters are already clean, my first guess would be the fuel lift pump… particularly if it is an electric lift pump. They get hot and lose effectiveness with age. High pressure pump gets starved for fuel and stalls. Happened to me (twice) on my Universal engine (which is a Kubota diesel) and once on a Beta on a boat I was delivering.

Contact Farron at Beta too - he is a great resource. PS - You were great in Miami Vice. All the best, Edd ———————————————- Edd M.

It started a while ago when idling. After some investigation and replacing fuel filters to no avail we found a loose clamp on the fuel line which was letting air in. Problem fixed. Sort off. It ran well for a while, but then....... and the new problem may be unrelated to this air leak problem. Now it stalls if it has been running hard for a while and you throttle down quickly. It also stalls occasionally if you are idling and throttle up quickly. For example when you are coasting forward into a slip and then want to stop quickly by hitting reverse. Sometimes it can be difficult to start after a stall. Sometimes not. If you change the throttle slowly, either when accelerating or decelerating, it keeps running. Filters are clean and no obvious air leaks or diesel leaks. Any ideas?
