If that is the case, pull the plugs and check for spark. If ok, need to do compression test on both sides to see what's up. Good luck.
Garden tractor losing power
Husqvarna LGT 3654 with a K66 trans swapped into it 2 years ago. Kohler 7000 engine.
Ran fine last week. When going uphill yesterday with my mower deck engaged, or when mowing denser grass (6 inches), the engine RPMs would drop and it would almost stall out. If I switched off the deck then power would return so it's not the transmission.
Edited to add:
Also, there's a pretty sizeable loss in speed upon engaging the deck on a level surface, whereas it used to be fairly smooth about the transition.
I replaced the air filter and fuel filter, that didn't solve the problem. Spark plugs and oil/filter were done about a year ago, I'm gonna swap those anyway, but the oil color is fine and levels are ok. Mower belt is less than a year old and was not a cheap knockoff, it's the real deal. Battery less than a year old, maintained on a trickle charger. No issues starting it up except when I replace the fuel filter it takes a few cranks.
What should I look at next?

My 54” went thru 2 trans drive belts due to worn pulleys. Replace 2 and she’s back to normal, I had those same symptoms
Could be the governor control linkage. I've had that problem when I engaged the mowing deck, the RPM would drop drastically because the governor did not react to the load imposed on the engine.

Check what searsnut said aboyt governor linkage. 1 more thing , coils can start a motor , but when u put a load on an engine they can crap out . Have the coil checked , or coils . I don’t know much a kholer 7000 .Check Float Level in Carb.

I’m sorry if you already seen this. LOOK AT SEARSNUT s POST ABOUT GOVERNOR LINKAGE . AND , COILS CAN OPERATE WELL ON START UP , BUT WHEN YOU PUT A LOAD ON THEM THEY CAN BREAK UP.Husqvarna LGT 3654 with a K66 trans swapped into it 2 years ago. Kohler 7000 engine.
