Yes. Sounds like "dieseling". The throttle is partially open when the engine is turned off. The hot engine has sufficient fuel to continue to run without spark from the spark plugs.
Clean the Throttle Body and you also need, at a minimum, the UIM cleaning using vacuum method. Maybe even a UIM/LIM rebuilding.
