Upon investigation it is definitely the News and Feeds tab on the taskbar. Upon first boot the news and feeds initiates and the memory usage ramps up, it quiets down after a few seconds. Then I deliberately clicked on the News and Feeds icon on the taskbar. The memory usage immediately started ramping up and within 2mins it used all of my 16 gb of memory.
The new update to the taskbar feature seems to be the cause and crashes the system eventually.
