My problem was a rogue app, I tracked it down to Youmail, once removed it no longer happened.
You might want to check out this thread on SOD:
Trouble With Sleep of Death on EB01/SuperClean 2.x? - xda-developers
I would also recommend moving on to the debloated EC01 rom, radio Just flash it in CWR, make sure to wipe cache and dalvik.
I installed SetPCU and put my settings at min. 200mhz. No more SOD and i still could use Youmail.
