Honestly, I had a 99 Ranger did the exact same thing and I thught the trans took a dump. However, as it turned out I had a failed input sensor (speed) on the transmission. Basically a little over a 100 bucks later and never had the issue again.
Also, should have looked first, but if you are bagged and not running wheel wells in front you need to look at your wiring harness that runs over the left tire. Rubbing through those wires will do the exact same thing.
