check out server error logs, hosting company find them , take look. information might in there.

are sure didn't install extension or maybe? if it's bad code or not compatable version of joomla every time runs crash, should evident in error logs.

your server logs different php error reporting , setting available in joomla, since can't access need find apache logs.
