Maybe your ME system is getting its power from something that isn't loaded by the chunk loader and therefore runs out of power?
A pretty easy way of checking if your chunks are loaded correctly is to place a ComputerCraft computer there and write this in the prompt:
This will open the lua prompt. Now leave the area (far enough for it to unload under normal circumstances) and stay away for say 10 minutes to be sure. Then come back and check the computer. If it's still in the lua prompt it means it and the chunk was never unloaded. If it's in the normal prompt it means it was unloaded and reloaded.
