If your EMS believes your input voltage is high or low, it will shut the AC down and then after a while will reset and try again. Have you checked your voltage at the pedestal. You may have too high a voltage. If it is borderline as your post indicates, you can bypass the EMS with the little slide switch on the unit. I wouldn't do this unless absolutely necessary as it bypasses the circuitry on the EMS and surges or other electrical problems will get through. If it is erroneously reading a high voltage when the voltage is normal, the EMS could be bad and need repaired or replaced.
Per conversation with a Progressive tech, we did bypass the ems by turning off the switch and he advised that we would lose a number of protection(s) but would still have high voltage protection at a minimum(?) About 1 hr after doing the bypass, we lost power for about 1 minute and again at 9:55P. That to was also off about 1 minute before coming back on and staying on. No further issues up to now. The Progressive tech and an acquaintance(who formally worked for cummins-onan in the shop both think it might be a pc board issue in the ems box. They reportedly will be sending another "logic" pc board via UPS to install.
