Sounds like its getting air in the system,Take your filters off and see if there full of fuel ,If not its sucking air before the filters. And this will not show as a leak

the secondary fiter will only be about half full after I turn the engine off have checked all fitting seam to be tight racor will be full so the air leak should be from racor to secondary filter which is about 5' of fuel line odd that gave no warning signs before it happened,thanks Keith

If you cant find the leak you can put air pressure through one of the feed lines{not alot about 10 pounds} and your air leak should leak fuel......

I agree with others the engine is not getting fuel - but why? If you have a check valve in the fuel line that is working then you likely have an air leak after the check valve and after the secondary filter. If the check valve is missing or leaking then the vacuum produced by fuel leaking back to the tank through the check valve coupled with an air leak after the secondary filter, is causing fuel to be siphoned from the secondary filter to the point where the engine needs about a minute to crank fuel back to start the engine. My experience with replacing filters is that the secondary filter must be filled to the absolute top for the engine to start promptly. Your engine should start in about a second. Remove the secondary filter, fill it to the top with new diesel, reinstall and promptly turn the ignition key.
Call Holland Motor Homes at 800-221-7197 for additional diagnostic help. If repair needed, take coach to a diesel shop in your area that has experience with Detroit Series 92 engines. Its possible you have a contaminated tank where fungus is clogging the filters reducing fuel flow to the point that high pump pressure is needed to supply the engine.
