you either need to replace your ECC sensor slash or turn everything off inside your truck your radio your AC put your windows up turn absolutely everything that's electronical off your lights anything like that then start your car let it idle for 15 to 20 minutes and Park and then that should reset your computer brain and you may not have to do anything else your truck may just fix itself. I know it sounds crazy but that's how I fixed my truck and it never broke down again after that.
