Being required to repeatedly sign in to eBay might be an indication of a problem with your browser not accepting cookies, or a corrupt eBay cookie.
Try another browser as a test to see if the same problem occurs. If not, go back to your original browser and check to make sure you are set to accept cookies. Try deleting your eBay cookies. With a corrupt or blocked cookie, simply deleting all cookies may not be sufficient.
Other things that can cause sign in issues: using private or incognito windows, or certain disk cleaning utilities that routinely delete browser cookies (there is usually a setting that allows you to exempt a site's cookies if you wish).
If the problem still occurs with multiple browsers, that might be an indication of an issue with your account itself.
Back when eBay changed the sign in page last summer, some folks using Microsoft browsers had issues with the "keep me signed in" checkbox on the sign in page not working correctly. There is an additional checkbox in the Site Preferences section of the Account Settings that can also be checked. If that box is already checked, try unchecking, hit "apply", sign out, sign back in and recheck that box and "apply" again.
