    Had similar problem on my machine when trying to run the motors too fast, they would work for a few minutes then started locking up and losing steps.

    I did what John has suggested to you and put a bloody big fan cooling the driver cards (2 in fact), never had a problem since. Other than that you could try slowing the steppers down a bit.
