1991 405GL Engine problem

This little problem doesn't happen all the time so I don't know whether to be worried or not.

Sometimes after a run of about 5 miles, the engine is switched off and key removed. The engine still carries on running.

Any help appreciated

pre ignition, basically a "hot spot" in the cylinder that automatically ignites the fuel without the need for the spark. check fuel mixture and ignition timing. steve.
