My 2005 Mercury Mountaineer loses power for no reason. This is the fourth time this has happened. It was been to the dealer multiple times and they cannot find a problem. There is nothing to foresee when it happens, the only consistency has been that luckily I have been on local roads doing no more than 35 miles per hour or so. First battery light and service engine comes on as the engine stops, then low oil. The car does not seize up, I can steer to the side of the road. If I put it back in park. Turn the ignition off, and then restart it is fine. There is considerable length of time between occurrences (months if not close to a year this time. ).
