When it stops, turn power off and tip the machine back against the wall. Reach under at front right and locate the drain pump. Place your hand on the coil part. I am picking that you will find it is very hot that is why it stops when it overheats. Only solution if it is getting hot is to replace it with a new one. Do not keep trying to run it as is because it will eventually damage the main control board. It should only be slightly warm to the touch after running for a few minutes.
