I have been having this same problem for 2-3 years now. I finally figured out that it had to do with either being on the http (normal) or https (secure) version of the site. Once I told my browser to always use the https (secure) version of the site, I have not had to re-login to the site, unless I specifically log out.

As a side note, my iphone acts stupid with the http (normal) version of the site. For instance, I do a Google search for truck stuff and it happens to pull up results from this site, they are always the http (normal) version of the site. If I follow the link, it doesn't recognize me as a member and none of the attached images show in the thread. If I change the http to https in the address bar, everything is fine.

I even changed my signature to the https version so if I click on it on my phone it takes me to the secure version an doesn't log me out.
