I would start with checking your own connections inside your converter / power distribution panel.
Look at the main connection first to make sure that it is not loose. A loose connection can cause intermittent failure, but worse yet, heat buildup and a fire.
Check the shore power cable itself to make sure there are no abrasions or other damage.
Check the plug end of the shore power cable to make sure it is not corroded or blackened from heat. Any bad connection will cause heat.
Check the seating of the main breaker. Pull the cover off with shore power unplugged and pull the breakers out and look to see if they appear to have corrosion or a bad contact. Also check the screws in the breakers themselves that hold the wire into the breaker. They can come loose.
