8 could be going bad, but I don't think that cause a no start condition or even make it die once you let off the starter. It would misfire and the exhaust would smell like fuel. Was your FICM voltage 48.5 in all 3 stages? Key on engine off, starting, and idling? I only ask because when my FICM blew out on me, the truck would only "run" while cranking. My volts were 48 but I ended up throwing injector codes 2,3,5,8 which are all on 1 bank in the FICM..turned out my logic side went bad. Unfortunately I was not the one that figured that out, I sent it to Ford and they ended up putting a known good FICM in there and she purred like a kitten again. Only 1 injector seems odd though if you're having the same problem. But going back to your hard start when warm, low pressure on the high pressure oil side could cause an injector not to work correctly..
Sorry I can't just come out and say exactly what your issue is, these beasts need good diagnostic work, but once you pinpoint the problem, they're pretty easy to work on
