Stronger needle, try a jeans or top stitch and Slow Down!
If you go too fast, you don't give the needle enough time to come completely out of the fabric. You move the fabric and because the needle's still in there, it bends just a tiny bit. Doesn't take much for the deflected needle to hit the throat plate and break. It's harder to bend a stiffer needle and by slowing down, you give the needle enough time to clear the fabric before you move it to the next stitch.
