On a 2006 Mercury Montego I recently got a failsafe mode message while driving. The engine turned off. I stopped and restarted the car. It happened ten minutes later. I have driven another 100 miles with no reoccurrence. Check engine symbol came up but went away after a week. What is happening

Hello, and thank you for your question. When you bring the car to the dealer they will more than likely find that the engine computer (PCM) has stored a diagnostic trouble code relating to the electronic throttle control! It probably has an intermittant fault in the throttle position sensor or the electric motor that opens the throttle plate! The code will need to be recovered from the PCM in order to be able to look up and follow a particulator pinpoint test the is listed in the manual!, there are literally hundreds of codes that could be stored and the actual code is needed to correctly diagnose the exact cause!
