My truck shut off 3 times today once driving to work and truck shut off but started back up on its own. on the way home hauling a trailer doing about 70 it shut off again but stayed off til i restarted. the 3rd timeit happen the same as it did the first time. I did a scan test with my matco scanner and got p0605. I have done some searching found similar problems but no answers on how they fix the issue. checked my chip and its tight and taped in so i dont think thats the issue newer ipr and icp about 6 months old and if it was that i think maybe a code would be present.
