Hi,
Did you notice if there was any noise associated with the failure? For example, a squealing or chirping sound? I ask because it could be the accessory drive belt (serpentine belt) may be losing tension and not turning the pump fast enough when it's under a load.
I attached a pic below and highlighted the belt. If you open the hood, stand on the passenger side front fender and you should be facing the belt. Check to make sire it is tight.
Also, when you checked the fluid, was it red in color (or pink)?
Let me know.
Joe
