Default [Q] Nexus 7 randomly restart then Kindle App shortcut is deleted

Lately I've been reading a lot more with my Kindle app and I can't go more than an hour without a restart. When it does, it also deletes the shortcut on the home screen. Would like to know if resetting my device may help this issue or should I just wait for an update from Amazon?

Nexus 7 4.4.2 Stock with GEL Launcher (was having same issue before installing GEL btw).
