Since your coach is 4 yrs old, it is probably in date range where most of fuel pumps were defective, but those pumps typically would fail very early in life...usually within 50 hrs. would know more if you posted full genset model, spec, & serial number.
your symptoms sound like fuel delivery problem for sure.

The genset is on a slide which is good/bad. Makes it a bit easier to do normal maintenance, but the way they have the slide set up, it completely blocks the access plate for the pump ! I won't get to do anything on it for a week or so.
