I had the same issues and I noticed the donation banner froze my install twice previous versions have been great but I'm having the same issues after 3 full wipes fresh installs and clean check sums I'm gonna have to revert back.

Really strange, I experienced three shutdowns two days a go as well. I went bed with a full charge, leaving it unplugged for the not. I woke up to my phone not responding to any thing. After a few attempts to turn it on, it finally vibrated and I saw the Samsung logo on the screen. When it booted I had 0 battery life left, it then shut down. I swapped batteries (official Note batteries) and booted it up, I experienced 2 more random shutdowns immediately after. This is happening with no tweaks or mods added to this ROM and after a good week or more of use without any issues.
I've since wiped and re-flashed the ROM, it's been running strong for a couple days now.
