This has happened to me on 2 occasions. I'm driving on the highway at 65-70ph when I feel a clunk and my power is suddenly gone. No response when pushing the accelerator, and the engine is running really rough, like the timing is suddenly off. I pull to the side of the road, the yellow wrench ight is on. I turn off the car, and immediately restart. The engine runs fine, no warning lights, no problems at all. I took it to the shop 2 days later and there were no codes showing and they drove around a lot, unable to replicate the problem. Has anyone else had this problem? My Edge is the 2013 3.5L 6 cyl AWD 80,000 miles.
