Strange Shutdown Issue

[jamesosully]

So I've only started experiencing this issue today but it is obnoxious. A few days ago I changed to the EC03 modem so I could get Bonzai 4.0. I decided to Odin back to Eclair and then update to EB13 so I could have more choices of ROMs. I switched over to ACE 1.7 last night, then to Baked Snack 2.1 and back to ACE. This morning when I tried to wake my phone up to make a text, nothing happened. Tried plugging it in and it wouldn't charge. The same thing has happened on Baked Snack too. Only thing I can do is pop the battery and restart. I restored back to Bonzai 3.1, but why is it doing this?

Any help is greatly appreciated!
