The problem started in fifth gear about 2 hours into a 4 hour trip. At between the speeds of 60 - 65 mph the jeep would all of a sudden jerk back and lose power all of a sudden. I pulled it out of gear into neutral and then put it back in fifth and it would go. But then it would do it again a few minutes later. Then after pulling off the road it did it in every other gear also.
This happened once before about a month ago. But it was not at all this extreme. But when I took it into carmax ( where I bought it) they said that they tested it and there was nothing wrong with it. That it was probably the oversize tires causing a loss of power. I have 31 mud terrains on a stock Jeep. I knew that wasn't what was wrong with it but I didn't feel like arguing.
Any ideas on what could be causing this? Also by the right front tire it looks like there is a light greenish/yellowish puddle after the jeep has been sitting there for long periods of time. This just started this weekend. I noticed it in my garage yesterday.
Sorry for the long post
