What gets hot? Can you leave you hand on the Gecko's for 2 sec without pulling it off from pain? Fans are magic things. Even small amounts of airflow make a big difference. If the motors are getting very hot then the encoder electronics may be the problem. You can track it down or you can just imporve the cooling to the component that is faulting. It sounds like a component is breaking down from the heat. I say that since it ran long jobs Monday and Tuesday but started to cause problems. Heat is rough on electronics.
