Engine running after key removal
It's called "dieseling". Your engine is so hot it keeps running even without spark to the spark plugs. The vacuum caused by the moving pistons sucks in more air/fuel, and this keeps the process going in a vicious cycle.
Checking the cooling system for leaks and flushing the coolant would be the cheapest place to start. Flush twice with distilled water and flush compound, then add a 50/50 mix of distilled water and antifreeze. This will also help your emissions, since NOx is created in a hot engine.
