my car goes into Limp mode after about 5 miles i pull off to the side of the rd and I pull the battery terminals and it resets everything and it will let me drive another 5 miles before going into limp mode again. Prior to this issue on 3 or 4 different occasions my car wouldnt start when i turned the key and i would have to take the battery terminals off for about 30 seconds then place them back on and the car would start up just fine. That OCCURED MAYBE 3 OR 4 TIMES within a years time frame. Any ideas?
