2023 Suzuki 9.9 EFI cutting out after 20 minutes

[rafsailor]

I have a 2023 Suzuki DF9.9BTXW5, runs great at idle but cuts out after 20 minutes, seems gas starved and also hearing a sucking sound before it cuts out then will not rev up after that. New fuel tank ,fuel line , gas and filters. Vent on can open. Gas is getting to the fuel filter. Decent stream form the water port and nothing clogging the water intake. This happened 3 x after the engine ran for about 20 minutes. Sucking sound is coming from the engine and not the raw water intake , then the engine stalls. Vacuum leak ? Any other ideas? Don't think it can be overheating as I have good raw water flow.

Still under warranty? are you getting any warning flashes from the red light?

Yes, should be under warranty but difficulty finding anyone who will work on a Suzuki. Did not notice the red light coming on.

Check the drain for the fuel cooler, there is a small hose that drains overboard when you drain the fuel system for the winter.
the screw is inside on the left side. make sure the drain screw is closed.
