so as stated previously, made it aboard the DAUNTLESS again today to try to isolate the issue with the port genset. this time started it as always at low RPM and allowed it to warm a little before dialing it up to 1800 and closed the breaker with no loads on the buss. This part always was never a problem and this time, I started to add load on the generator by using the galley range. Nothing happened to the gen with only a burner so lit up the entire range and still no problem with the generator maintaining rpms. Pretty soon I was adding loads everywhere I could and still no problems. Closed the breaker to the battery charger and then went to start a main (which before was the beginning of the cycling issue) and even with the charger putting out 80amps the genset just kept on going as before with it putting out 20kW of the 45 it is rated for. Never once lost rpms and when adding loads only a slight change in its sound as the loads hit it.
so now I have no clue as to what was causing all the trouble last weekend but the problem is now gone (at least for the time being) and will just wait to see what happens the next time.
