ford 7.3 don't want to start after warmed up.

93 ford 7.3 starts good when cold, after it runs 30 minutes & it sits awhile it dosn't want to start with out a shot of starting fluid,( I have a switch so I can disconnect the glow plug heater) to avoid problems. It has new filter, new lift pump, new injectors, new injector pump, glow plug system works good. It runs great when started.
Any Ideas?
Thanks Dale

Could be timing. Who set it when you had the pump installed.

That mark is a starting point to set the timing. You should have it set by someone who has the tools to do it.

do you know first hand that if the timing is off a little it will cause this problem?
Thanks

Next time it doesn't want to start, take out the fuel filter and see if it is full of fuel. If not then fill it to the brim and try to start it. I had a similar problem with cold starts that turned out to be a leaking fuel line. Filling the filter helped it start right away and it would run and start fine, unless I let it sit for more than a day or two.
