Run this for your domain. http://tools.pingdom.com/

It should help finding out what file its held up on.

If that doesn't put this code into your wp-config file.

// Enable WP_DEBUG mode
define('WP_DEBUG', true);

// Enable Debug logging to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);

// Disable display of errors and warnings
define('WP_DEBUG_DISPLAY', true);
@ini_set('display_errors',10);

// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define('SCRIPT_DEBUG', true);

This should help find the file its held on. Then you go from there.
