More than likely, the good hard workout that you gave it got some carbon in one or more cylinders hot enough to ignite the fuel that was coming into the engine during shut-down. Remember, the only think you do when you turn the engine off is to stop the electric spark to the spark plugs. Fuel and compression are still present (even with the throttle shut) and if there is another source of ignition (like hot carbon) in the cylinder it will ignite the gasoline vapors still being pulled into the combustion chamber, which is sometimes called “dieseling” (since no spark is used to ignite the fuel) causing what you describe. I would suggest that when this happens, you turn the engine back on and let it idle and cool off for a couple more minutes and then shut it down.
