shore power
2008 discovery 40x. At some campgrounds when on shore power, our whole electrical system shuts down, (no power). Go on generator and power comes back. We "re-set" the inverter and go back on shore ...

Check the voltage at the pedestal, then inside your MH before you turn things on and after plugging in a higher wattage appliance (hair dryer, etc.). If it plummets after turning on a high wattage item, it's the CG that's at fault and there's nothing you can do except for using an autoformer or the gen. You can try finding a site close to wherever a power transformer is located which may help.
If in an older park, the wiring is just too small for all the 50 amp RVs nowadays. It may look perfectly okay before plugging in, but if the wiring to the pedestal is too small, the voltage drop will too great and an EMS will trip. The NEC has changed a lot since the 60s when only 5% of park pedestals were required to be 50 amps. The latest NEC requires 20% to be 50 amps but that's still not enough for all the various RVs that have 50 amps now.
We were just at a Thousand Trails CG where the voltage was only 106 before we turned things on (we have 30 amp service). Wasn't long before our EMS tripped on low voltage. Tried another site and still no good. Then moved yet again to a section that had all 50 amp pedestals and it was fine.
