When I have seen this really weird problem on Jeep, it has been a defective throttle position sensor. The funny this is, the little bugger will not set a code. When it acts ups, it is usually after a 1/2 hour of driving and then on the freeway the car just seems to go into neutral, it is because the sensor starts telling the computer that you are trying to down shift, when you are not, so the transmission gets stuck in a no-mans land type of gear or neural position, and the engine just revs and revs.
