I have a 2010 Mack chu613 with mp8. I was driving down the road truck just shut down while driving. Was able to pull side of the road turn it off then on started right up. it did it again 30 minutes later. now I have no dash accessories when the key is on in the truck will not turn over, it shuts off as soon as it does it’s cycle of checking relays. I replace the three relays on the top of the dash to the left of the fuse panel. It is still doing the same thing all my fuses are good through the truck I’m clueless any suggestions please would be grateful!
