O.K., so I was able to replicate the crash that I see each time. I replicated the crash twice. Both crashes were "on air" crashes. The first crash happened in just over thirteen minutes (13:08 to be exact), and the second happened after 12:20. This is consistent with what I have experienced on Sundays.
To be precise, here is the sequence that occurs each time. After 12-13 minutes I get a prompt window that says "Developer Tools Access needs to take control of another process for debugging to continue. Type your password to allow this. (I took a picture that is also attached...this and the crash...sorry for the phone pictures, I couldn't take a screenshot as system was hanging)


From this point, no matter what direction I go (allowing DT Acess or trying to switch applications), The entire system crashes and I get the grey restart screen: "Your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up."
