Most likely you have a high pressure oil leak. When the oil is cold and thick, it doesn't leak as much. When it hot and thin, you can't build enough ICP at cranking speed...that's why the spray helps. When you get it to spin faster, you get enough ICP to start. Could be bad injector or injector Orings. Pull the intake/valve cover and watch the injectors while someone cranks it over hot. High pressure pump would be last thing to check after you rule out leaks.

Is it a Maxxforce engine with DPF? I would be suspect of the o-rings from the high pressure oil rail to the injectors leaking.
