Did you replace the fuel itself?

Is it overheating the engine? That makes my similar L185 also seem to be running out of fuel even before it gets HOT. You might try cleaning the screen in front of the radiator, check radiator fluid and engine oil. (I doubt it would get that hot in your neck of the woods right now)

Please provide more details about what you are using it for in the 15 minutes that it takes to power down. Is it at idle or running wide open throttle?

How long ago was it when it ran fine? Was it idle for months or do you use it every day?

Could be fuel delivery issue or could be the injectors are failing when they get hot.
It could also be another issue with the engine.

Any smoke when it has this power loss?

First thing to do is eliminate it being a fuel delivery issue.
You need to bottle feed the injection pump.
You use a bottle/ jug/ container and direct feed the fuel injection pump.

You will need to stop fuel flow before the lift pump, so pinch the fuel line ( or shut off the valve is so equipped) before or right after the fuel filter.

Then remove the line off of the side of the injection pump and feed new clean fuel directly to the injection pump.

Get back to us on how it runs after that test.
