My mercury turns off while I am driving it ...but will turn back on

Hello Valerie. Ford had an active recall out for the explorers and mariner's around the time yours was made. There were some overheating electronics that caused the car to stall randomly. Here's an article that helps explain. I'd check with your dealer to see if your car is eligible for a recall service. https://www.nytimes.com/2014/09/13/automobiles/ford-recalling- older-escapes-for-a-stalling-problem.html
