I have the z force with the Kholer engine.
Lately, after running for 15 - 20 mins, it stalls while the PTO is engaged.
For some reason it only does this when the throttle is wide open. If I run it on quarter throttle it wont stall but then there's the problem of not enough power.
I originally thought that the fuel pump wasn't delivering enough fuel to sustain full throttle but it only does it while the blades are engaged.
Any thoughts?

Sounds like an obstruction to the fuel system somewhere.
When the blades are running the the throttle is open wider so the engine needs more fuel.
Start with removing the float bowl and checking for water.
If it is clean then check the tank vent.
Neither of these would be warranty items as they would be considered maluse by the customer.
It could also have an air leak around the manifold .
