Select Tools-Internet Options under the General tab to see if "Delete browsing history when exiting" has been clicked. If so, tick it off. If there are no points, then you can select "Settings" to view your historical days. Is it too short? The default value is 20 days. If you change these settings, this problem should be solved. You can also try resetting the browser to see if it works. You can go to Tools-Internet Options-Advanced tab, find the "Reset" option, reset the browser, or reinstall the browser if it fails.
