Ford 4000 4 cylinder diesel starts and runs for 15 minutes then stops. If I wait 30 minutes it restarts runs again for 15 minutes then stops again. Anyone know how troubleshoot this kind of problem? Its a 1964 I think.
 
Might check fuel tank cap, when engine quits remove cap to see if there is a vaccum had this on 8000, sounds like same problem. I don't know how your tank is vented, it has to be either the cap or some other means.
 

As Bern said, most likely a restriction. Could be screen in tank, could be the filter. it apparently runs for a little while so when checking for flow insure that you have a steady stream for AT LEAST thirty seconds.
 
Sounds like a flex ring issue. loosen the timing window on the side to bleed off excess pressure. If the tractor keeps running you have a a bad ring. A simple reseal will fix the problem. Should cost about 350-450 to repair. Call around and price shop. Just make sure who you pick has experience . I have seen some real expensive mistakes made by the neighbor guy who said he knew what he was doing. I would be glad to help you out if you cant find someone in your area at a fair price. Good luck,,, Al 231/757/0064
