Running out of gas maybe?
Check the fuel flow but I think since your 1200 has an electric pump it will start to tap rapidly if it's not getting gas but it could also be a bad pump.
Ya know, could be many things but I would start with checking fuel delivery, the easiest stuff first then make your way into it further.
Also if the gas cap vent is plugged the vacuum created in the tank can restrict fuel flow.
When it starts acting up, loosen the gas cap and see if it improves.

Look at the plugs. Check compression. Check to see if the fan is coming on. Check the radiator is full and the fins are clean. Check for weak spark. Excessive spark plug gap. Clogged fuel filter. Well that should be enough to get you started.
