I have been having intermittent problems and can't seem to find what is going on. I have a 2001 ISX 565 that after running for a while I shut it down do what I have to do and go to restart it, it will start fine and then sound like it runs out of fuel and will not restart. (To restart I have to use ether) I do not have an electric fuel pump so that is not the problem. Fuel solenoids have been tested and replaced. ANY HELP WOULD BE GREATLY APPRECIATED!
