My vehicle shuts off while driving. No warning, loses power steering, loses power brakes. It will start righ back up once I shift into park. This happens at all different speeds and temperatures. I could have just got in the car or been driving for hours. Happens at 15mph and 60mph just the same. Have almost been hit from behind of several occasions when this has happened.
This vehicle idles very low and stalls at various speeds. No warning is given engine just shuts down. Spark plugs have blown totally out from the engine several times.
04 Mountaineer cluster gauge blacks out then meter gauge flickers. Waited for 10 min I'm parking lot then it comes on. Started to drive then about a mile into driving it shuts down. Mind you my SUV was still going but gauges shut down then my lights go off, then my windshield wipers go. By the grace of got I got home. While on road my engine was struggling. Help before that incident I had just replace thermostat housing because it cracked and I was loosing coolant.
