My Mack cxu613 losses power here and there. I keep changing fuel filters but issue keeps coming back. I'll be pulling a hill and it losses power n crawls up the hill in 3rd gear. Sometimes after the hill I'll loss the throttle and then coast to a stop n the truck shuts down. It'll fire right back up but with the same power issue.
