Narrative:
The airplane performed normally as I landed ZZZ; departed there and flew to ZZZ1. After landing on runway xx; I had a long taxi on the runway to get to the turn off point. Since it was a long taxi on the runway; I started doing the after landing items while still on the runway. I shut off one fuel valve; retracted the flaps and moved the fuel condition lever to the low idle position. While moving the fuel condition lever; I accidentally pulled it slightly past the notch for low idle and into the fuel cutoff area. The engine shut down. As soon as I realized the engine had shut down; without thinking I moved the lever back into the low idle position believing that would keep the engine running. The engine did not keep running or restart. I then moved the lever all the way into fuel cutoff; waited for the engine to slow down; turned the fuel valve back on and restarted the engine with the starter. The engine restarted. The engine instruments appeared normal during the restart. I continued taxiing down the runway; then to parking and shut down normally. Upon preparing to depart; the engine lost power on taxi out. A tug was required to reposition the aircraft back to the FBO. I later found out that there was severe damage to the engine.following normal procedure and waiting to clear the runway before completing the after landing check list may have prevented the engine damage. Several of the same model aircraft that I fly have a positive lock out for the fuel cut off position. This would've prevented me from moving the lever beyond low idle. I also believe that a placard with a warning about moving the fuel condition lever to low idle after an accidental shut down may have prevented the damage.
