2000 35 hp 3 cyl Johnson, well maintained, low hours. Key switch left on 2 weeks, battery dead. Put in fresh battery, went fishing. Ran fine 1/2 day. On way back to dock, motor stalled. Restarted right away, whenever it gets up to speed, it flats out, if throttle is closed immediately, it keeps running at idle. Acts as if it runs out of fuel. Fuel lines and filter clear, rebuilt fuel pumps. Took out for test, started fine, ran about 90 seconds at speed, flats out again, repeated several times, idled to dock. Visual checks of ignition shows nothing of concern. Where do I go next?
