Google Base XML Cron GET Feed

We have a store that only recently something happen and it now will not automatically feed into our Google Base account. The manual process works just fine with both Zen Cart link in admin, and uploading manual to direct to the Google Base by loggin in and browse. We see in the feed folder the file is generating okay, but the feed times out error 500. We believe that not to be the problem however and we think it is more of a php issue or how one of the files is set. We say this because we have 5 other identical stores in which work as designed with no issues. We think it should be somewhat easy to trace the issue using the access to the others that do work fine to see if there is any relating issues or differences. This task will be simple for the person WHO KNOWS ZEN CART, GOOGLE BASE, AND CPANEL CRON JOB SCHEDULING. Please help we don't have much money!!
