I have a 2010 ford edge sel awd. I'm having an issue where when I drive the electrical system will randomly cut off after all the dash lights flash. the engine is still running but I lose all power. The car will start with no problem every time I start it. When I check the battery with a multimeter while the car is on it is around 13.25-13.5 then when i press the gas, I'm at a solid 14.0 but I can't get a read on it when the power is off because it only happens while driving. If anyone can give me a thought on where to start or what the problem sounds like that would be awesome. I'm going to start with the serpentine belt while I take my alternator to be tested but I would think I would have trouble starting the car if it was that.
