Perhaps there is an ebook on the device that causes problem when the library index is being constructed. You can disable the indexing via Settings->Advanced_Settings->System->Library->Library_Data_Update. See if your resets stop happening. If so, you'll have to find the book that is the problem and remove it.
Otherwise, if you have WiFi available and aren't afraid of the Unix command line, you can install my utelnetd daemon and log in to the device from a PC while you're reading with it. You can monitor various things (kernel messages, free memory, CPU usage) to see if something stands out. Hopefully, it's a software issue rather than failing hardware.
