There is no way to specify a maximum run time when sending a query to the server to run.

However, it is not uncommon to have a cron job that runs every second on your database server, connecting and doing something like this:

2. Find all connections with a query time larger than your maximum desired time
3. Run KILL [process id] for each of those processes
