"One of my 9.9 Yamaha, high thrust, 4-stroke motors, has an intermittent issue with stopping. This weekend, ran fine for about two hours, and then kicked a couple of times and died. Pumped up the bulb, and started immediately. Ran for 20 minutes longer, then died. Started it later on, and it ran fine. but this has happened many times before - usually after a couple of hours of motoring. Cooling system is working fine, and the area below the cowling is only warm, not hot.
Put in a carb rebuild kit thinking maybe it was a float needle sticking. No evidence of any problem with the one I removed though. Ran fine coming home - about 3 hours of motoring. If the problem persists, what's next? Fuel pump? Is there a kit to rebuild, and how difficult is this. Any other thoughts on what the problem might be?"
