With the implementation of 'Safedock' at my station, I've noticed it happens a hell of a lot more often with a particular LCC who have a large fleet of 738's.
Only a couple of weeks ago the captain cut the engines about 20meters off the stop bar, presumably coasting to a stop. Catering truck started to reverse off the next stand so I hit the emergency stop button. Aircraft stopped, half on the taxiway, half off stand.
Once the obstruction (catering truck) was clear Airfield Ops came to marshal the aircraft on stand, which had no power
He spent 5 minutes blocking the taxiway while he restarted the engines to come back on stand.
