Welcome to MLF.
Have you check the spindles to make sure one has not seized up?
Check belts and idler pulleys as well.
Make sure there isn't a problem with the electric clutch.
Are the spark plugs clean? Replace every 100 hrs or once a year for them is a good rule of thumb.
Fuel filter clean?
Maybe run a little seafoam in your gas.
Could be a fuel flow problem depriving the engine of fuel under load.
These are just some suggested ideas for you to check out.
Let us know what you come up with.
