I play MC 1.7.10 in Offlinemode. With Java 1.8 and 5 Gb Ram.
My ME Sytem Shoutdown rendomly.
Tryed to reinstall Mc and AE2.
Also I tryed other AE2 versions like rv2.stabel. Tryed more Ram for Mc.
Also i tryed AE2 without any other Mod installed.
All of this dident help. This are my Mods that i normaly use pastebin.com/Eq5frkZC.
It worked Fine for 2 Weeks. Is there any Mod Conflig knowed from the Mods i use without Optifine ?

Okay never mind. This Ticket can be closed it is a Chunk Loading Problem caused by a chunkloader that i forgot to destroy as i build a biger Workspace.
