Default Device doesnt boot..usually, dies within seconds.

My Nexus 7 (2013) was working great, I updated the Cyanogenmod to a newer nightly and now the device wont boot...usually.
Sometimes it will make it all the way to the OS and then 5 seconds later shut off instantly. And then sometimes it wont make it past the boot screen. Sometimes it doesnt even make it there, If I boot into recovery it shuts off instantly too, fastboot mode gets about 7 seconds before that shuts off too...

It's been charging and says it has a 40% battery..

It's really odd. Help?
