While driving in four wheel drive, either in 4hi, 4lo, or 4x4 auto, after about 20 minutes if driving the oil pressure will slowly drop to 0. After a couple hours and if I switch it back to two wheel drive the oil pressure will go back to normal. I was told it could be a faulty sensor, but I would like a second or third opinion. Any advice is appreciated, thanks.
