Onan 4000 in 2015 Sunseeker 3170
I posted something similar in the technical thread as well. Last year I only used the generator when stationary. It worked very well. This year the generator was stalling out after about 10 to 20 minutes. I replaced oil, spark plug, air filter, fuel pump and filter. The generator sounds good and now runs for hours when not moving. After about 15 mins of driving the generator stalls. Oil level looks ok and had a full tank of gas.
