How's it start after it's hot?
I'd learn towards HP oil system drainback/leak, or the LP oil system losing prime. More so the HP oil system leak if it cranks over longer or wont start once it's hot.
It may have a SMALL leak, enough to allow the high side oil system to drain overnight but still be overcome by hot oil. Typically once the oil gets hot and thins out the condition gets worse, but if it's something really small like the plug that goes in the rail where the ICP sensor would go if the rail is on the RH side, this could be your culprit. Just fixed one in a LCF a couple weeks ago.
Could also be a sticky IPR or weak/failing HPOP.
If you have a scan tool, monitor IPR and ICP voltage when cranking, also at hot idle.

I just fixed one with this problem my self. I replaced the glow plug relay and the napa oil filter/cap. Should have done one at a time.

I'm having the same issue, How did you know it was the relay for the glow plug? My scan gauge showing no codes.
excessive key crank in morning normal temp. cranks fine thought the day.
runs fine no smoking even after getting it cranked.

Did you ever figure it out? I'm having same issue.

We replaced the glow plugs and glow plug harnesses and relay. Im positive it was just the relay tho. Ohm test the plugs just in case. Mine are all good. Just if I'm gonna fix somthing like that ya might as well do all of the job. Just like not changing the rotor and cap when you change the spark plugs.
I fixed issue.
