When my car was in park, was in idle and the air conditioner was on, after some time the motor turned off.

Idle Air Control Valve (IACV): The IACV is responsible for regulating the engine's idle speed.

I just purchased this car listed above from auto nation and all systems were in good running order. A service person said that some Ford Focus's automatically shut off if you have the car in park and it has been idling for too long. What do you know about this?

I don't know if the 2010 has the about shut off option but you never know, if it does have the option, it should have a switch on the dash that can cycle the system off. If not, we should do a CAN scan, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:
