My 6.5 diesel will start in the morning and run all day long but if I turn it off for a hour or so it will not start again until it cools down. I have changed the fuse relay, low pressure fuel pump on the frame and the high pressure mechanical pump for the injectors and also the oil pressure switch. There is an electrical component on the bottom of the fuel filter that I have not changed. Any ideas?
