Do you use extensions? I've experienced this (in Fedora 21 to 23) but since I stopped using extensions, I haven't had a single crash. I usually run one session on the laptop for 5 days straight.
I am not going to use gnome with out extensions . Never ever ;)

During login try picking X.org instead of Wayland, you probably have something that doesn't play nice with Wayland yet.
Have used it for long time? It is really buggy. After awhile it literally slows down. I keep my workstation open for at 2 days and after 7,8 hours it gets slower and slower m.
And sometimes it crashes badly. That should not happen with desktop environment.
