I have a Caterpillar C-13 in a Freightliner 2004. Truck runs and motor dies immediately. I let it sit five minutes and it starts up right a way. Sometimes it runs for six months and sometimes it only runs for 20 miles. Recently when I start it up I can run 10 miles, then I the digostic lamp starts to flash and goes away after a while. I get a several codes 94, 95, 72,73,74.We had it in the shop last year, they overhauled ECM, Replaced wiring, actuator oil pressure switch, and it still does the same thing. Does anyone have idea what the problem might be?
