My 2005 Ford Explorer will stop in traffic, the oil level light comes on as low, then, the vehicle engine power cuts off. This could happen once a week, once every two weeks, or twice a day and then not again for a week. I turn off the ignition, restart it and go. I had the oil changed. I had a new oil reset button put in. No one can see the problem because it doesn’t happen when being testing-it hasn’t yet. It’s a mystery? Please help?
