help understanding naval supply, problem in pacific

[General_Jah]

First let me thank everyone for helping me with so many questions you guys are great.

I am still in my Japan game and trying to island hop to the US. It's going well but for some reason all of a sudden my fleets and armies in and around pearl harbor keep running out of supply. I have supply convoys automanaged and am not real clear on how this could be happening or what I need to do to make sure it doesn't happen.

Have you built lots and lots of spare Convoy ships? Are too many tied up on some stupid supply mission? Have you waited a few days with your fleets at sea, to allow the Convoy routes to adjust?... it often takes two or three days.

Try turning Auto-Convoy off, cancelling all your Convoy routes, running the clock past 00:00 hours, then turning Auto-Convoy back on and again running the clock past 00:00 hours.
