Battery 100% to 0% then shuts off

view story

http://forum.xda-developers.com – I have been monitoring this for a while now and in several different mods etc. It seems when I leave my phone plugged in fully charged with the screen on it will at a random times just think it has 0% battery even when plugged in it will then shut off. Battery temp is a little high at around 40c. Can't find any running app or process that is throwing up any red flags either. Any ideas? As you can see in the images it just almost instantly drops from 100% to 0% and then shuts down. It doesn't reboot...just shuts off until i power it back on. Attached Thumbnails (HowTos)
