It sounds like it is not getting enough fuel,check your fuel filter to see if it is plugged.It is along the frame on the drivers side just behind door.You will need a quick disconnect tool to get it off.Might not be the problem but that's the first thing I would check.Because of there location this filter does not get changed often enough.
Check to see that your catalytic converter is not full. Otherwise get your engine tuned up.
I had one do that and it was caused by a bad intake valve.
check your timing and vacuum advance and vacuum leaks. from there check fuel delivery system.
sounds like it could be the timing when it's under a load.

A timing belt installed improperly would cause a severe loss of power if it ran at all. Check the firing order, condition of spark plug wires, distributor cap (if applicable) and spark plugs.
The 'type' of power is determined by the load. If the load is resistive (e.g. a lamp) then the rate at which it consumes energy is termed 'true power', expressed in watts.You seem to be under the impression that reactive power is 'pushed out' into a load. This is quite false; the loaddetermines the power.
There could be loose rings in the engine that would cause this. The valves on the engine may also be chattering.
Usually it is related to fuel since the engine consumes more when worked(under load.)
Assuming the generator converts 90% of the mechanical power into electrical power, it has an efficiency of 90%, which means it consumes 11 kW of mechanical power under a full electrical load of 10 kW. Under no load the frictional losses will still apply, but the resistive losses in the windings will not be present. Therefore the no-load losses can be estimated as 500 watts in this conditon.
No, the transformer has to supply the load, whether it is light or heavy.
If its a 4 stroke it sounds like a burnt valve or head gasket, if a 2 stroke a bad pack,coil or keyway can cause this,...
