In your Magento directory is an .htaccess file. Open it and find the following lines:

php_value memory_limit 128M
php_value max_execution_time 18000

Increase the memory_limit to 256M or even higher if you like. Confirm the change by creating a file in your Magento directory that looks like this:

<?php phpinfo();

Access the file by typing it's name directly into your browser, you should be able to see what memory_limit is now.

If setting limits doesn't work I suggest turning on flat catalog or use sql. I provided a link-only answer that is now expired, but the WayBackMachine saved the day (http://web.archive.org/web/20110112232603/http://basdebie.com/magento/magento-export-time-out-try-plain-sql)
