I agree with Pat. And there is really no easy "fix" to this.

1. If you want to run these motors, you probably have to get a better board/ESC that can handle the current. Email the people you bought the motors from and ask for what recommended tank electronic to run them. Ask for the motors continuous current and peak current are also useful to know.

2. Use old motors or get motors with current that matches your board motor controller. For example, these promax 480 motors (ACC348) draws only 12A max and they are very strong. (http://www.maxxprod.com/mpi/mpi-10.html)

By the way, what electronic are you using?
