Well sounds like you've been busy. Ive had more than my share of hard starting vehicles.
My old 4Runner was that way. Would cold start like a champ, but if it ran for much time at all, it had a hard time starting, got to where it wouldn't start at all without at least a 30 minute cool down. I ended up replacing the fuel pump before I sold it and it took care of the issue. Didnt make sense since it would start fine. I suspected the pump, but was trying everything to avoid dropping the tank. Might give that a check.
