Consequence of off roading. I understand that for every hour on the track or hills there are 4 to 5 hours spent in the shop. I just don't see the fun in that.

Your problem, have you thought that you may have taken out a motor mount? Start there.

What kind of damage to the wallet would that make to get repaired?

First of all test to see if it is a motor mount. They aren't but an hours worth of work to replace. Test the mounts by letting out the clutch with the brake on slightly reving the engine. Have someone help you and watch the movement of the engine. It should NOT move around a lot. A small amount of movement is normal. Do this several times and also in reverse. The mounts can look good sitting normally but putting pressure on them will show which might be at fault.

I've had problems like the one you've described. On older vehicles the problem stems from getting water or mud into poorly guarded ignition systems and shorting out the points and/or frying the condensor. On newer vehicles like the one you describe most ignition systems do not have points or a condensor, but they do have a system where every cylinder has a coil that is connected not only to a spark plug but also to the ignition control module or vehicle computer. Mud or water may have shorted out the connection to the two cylinders you describe.
