Ive had this a few times with these engines, it will be the valves sticking in the cylinder head, engine runs fine untill its worked hard and gets hot then it drops off a cylinder as the valves start to stick and do not seat propperly.

It will need the cylinder head off to clean the valves and guides up unfortunatly.
