Check your battery...I have had the same problems with my 2165, but it is because my battery was not holding a charge. Since the eletric PTO is powered by the battery the mower will die if the battery is not charged or is not holding a charge. I would first connect a charger to the battery, put the charger on boost or Start setting, start the tractor, start the mower it should continue to run while connected to the charger. If it continues to run I would replace the battery. Check your battery...I have had the same problems with my 2165, but it is because my battery was not holding a charge.
