I have the same problem. When this happens and only happened twice in the same terrain on two different years. I was traveling in hilly sandy terrain it is a 28 km stretch and could not get much road speed. I was also pulling a tub trailer loaded with gear and the sxs also loaded. When this would happen the trans defaulted and would not shift,speedo was inope and light on in the dash .Same as the other reports. i would disconnect the negative battery post , and then reconnect it. The unit would work work normal for a while and then act up again. When I got off this trail and got on the next section of trail which is wider and less steep of hills I was able to get more road speed. It never acted up again for the rest of the trip. 50km.
