first thing would be to actually look at the processlist in mysql so you can see what's running (and how long it's running. if it's heavy, you usually have a couple of seconds to see the processes). if you don't find the problem, ask your administrator to enable the mysql-slow-log, so that all slow queries will be logged to a special log file.
