Sounds  like a classis case of "Heat Soak" to me.either there is a leaky
injector or a bac check valve i nthe Fule system that lets the pressure
drop off and the engine hear boild the low pressure gasoling causing the
equilivent of the old "Vapor lock. SO until the engine cools down it
does not recieve enough liquid fuel to start.
There is a port o nthe fule system where a pressure gauge can be
installed and one can do a leak down test.
Recomendations vary but the pressure should not leak down faster then 2
PSI per 5 seconds. It typically should be much less than that.
