I drive with my mechanic every so often and on one occasion when I showed him how long it takes to start the truck, he said the ball valve in the fuel pump (or regulator, I forgot which one he said) is getting stuck and by holding the key for longer it builds enough fuel pressure to overcome the ball's 'stickiness'.

Maybe it's something similar? Have you tried running a fuel system cleaner?
