I believe that unit utilizes a centrifical clutch. try decreasing the idle speed and see if the tines stop. They should then engage as throttle is increased.

check the shear pins on the tine shafts

I had a similar issue. Tiller starts and runs for 20 secs. or so then dies. Found the problem! In turning the tiller on its side to check model numbers etc. the fuel line had shifted inside the tank and was stuck just about at the TOP of the fuel level. When I gently pushed the fuel filter and line back to the BOTTOM of the fuel tank, the tiller now runs beautifully! So, check that the fuel line placement inside the fuel tank is correct.

This seems to be a common issue as of late, i'd tighten up your idle adjustment so you can run at full throttle with no issue. The tiller's oil should be at the lower lip of the dip stick's access threading while the unit is laying face down (gas tank down). Clean up your carb as well and change your plug/filter, if this doesn't work than you're probably looking at some simple carb adjustments, but the fact it dies after 10 minutes of use makes me think it's running either dirty or too rich.
