The generator powers the refrigerator and charges the batteries, so I don't think its an issue at the generator.
Given that the A/C works off shore power this would lead me to believe you might have a high resistance contact problem in the Transfer Switch.
As for the Sirrus, the "Loading" message on mine indicates it is attempting to load or access the CD/DVD. Maybe there's a bad CD that it's trying to access? In Sirrus mode you'd normally see errors like "No Signal" or "Antenna Connection Problem".
