when I am riding my 2008 Rincon when the ambient temp is warm 70df + slow climbing in 4x4 in auto after about 1.5 hrs the digital speedometer will start showing 0-99 mph and the 4x4 light will go off and on as will the esp light and it will shift into another gear even though it was in auto shift and sometimes it will die but restart. I will let it cool for about 15 minutes and everything is normal but will do it again if I work it again. I have taken it to the dealer twice they cannot get it to do it and it doesn't give any codes. any body have any ideas. thank you,elkhunter001
