I have a '98 Dakota 3.9 two wheel drive automatic standard cab 300,000 miles. I have a question concerning the computer. I have intermittent sudden shut down and most times it will restart with no problems. When it does not restart immediately it will restart after waiting a few hours(cool down). I have replaced the crank sensor. Could this be a coil? My first question is has anyone experienced this? Has anyone used one of the computer re-manufacturers? My last question is can a salvage computer work as long as the options are the same, can a computer be reset without going to a dealer. Thanks for your time and help.
