Losing power while plugged into Shore ? Follow up more info

50 amp, plugged into shore power. It's 98 degrees outside, running both AC's, TV, Direct Box and frig.
In the last couple of hours, I've lost the power 5 times, after 30 seconds to a minute, it comes back on. I called the office and they're not losing power. What do you think? Is it the shore power end, or something in my motor home? Thanks

I'm on the end of a row, the camper next to me, has lost power also. His breakers are popping.
Maintenance checked my pedestal and one was 113 and the other around 119.
On my Progressive Industries EMS-LCHW 50 which has surge protection, I'm getting the following readings.
L-1 108V 8A Code EO low voltage
L-2 116V 21A Code is good.
Class A

    108 volts is too low and your equipment is doing its job by disconnecting. 108 volts can damage high demand appliances like an air conditioner.

    Low voltage is shutting down the EMS.
    You need to check the voltage at the pedestal. Odds are the campground has minimal voltage. Then you and others operate the AC units which causes the voltage to drop below set point in EMS.
    Make sure you water heater is running on propane and not 120 volts while AC unit on same phase is running.

    It can be the campground electrical. There was a campground I worked at that had 3 sections wired seperately. The oldest section could not support all the rv's running everything, especially all the AC's when it got hot. One weekend while working the power would go out (main box just about burning up) wait a bit, turn it on and everyone's AC's kicked on at about the same time - that would trip it again. Could not get them to understand that everything coming on at once was also contributing to the problem. We are talking an area with about 50 rv's. Campground and county admin knew about the problem, but planned on redoing that whole section within 2 years so were doing nothing about the electric. Only happened when they were full like on a holiday weekend. What a pain as the campers took their anger and frustration out on us workers. We couldn't do anything about it. Stuck between the powers that be and the campers.
