If the fuel line has a filter on the end of it at the bottom of the fuel
tank, it can suck fuel until it clogs. When it stopped sucking the fuel
up (engine stops), it unclogs and then sucks fuel to the combustion
chamber again....until it clogs again. Obviously, the time of this
process varies (as it has for you). If it doesn't have a fuel filter at
the bottom of the fuel line in the tank, then it is likely a clogged
fuel filter elsewhere. If you change the fuel filter on the engine, and
it keeps happening check the tank idea. Some Universal engines had that
problem.
Good luck.

Subject: Stus-List Diesel issues
On the way to and from our racing area, my Beta-25 with only 390 hours
on it was running fine and then it dies.
It started up right away, ran for a few minutes then died again.
We sailed out of the channel for about 10 minutes, started it up again
with no problems and it ran for 20-30 minutes before
I shut it down for the race.
On the way back we motored around loafing at about 4 knots for 30
minutes as we headed for the channel back to the slip.
Halfway in it died again. I used the electric fuel pump to be sure it
was 'primed' and it started right up and then quit again after about
30 seconds.
By then, we were close enough to the slip to sail in--kept the main up
for just such an event--which we did without issues (a competent crew
of 6 can do that!).
Ran it in the slip at full throttle and it died again after about 3
minutes. Started tight up, ran again at full throttle and it died
again.
Fuel tank is only 3 hours into a full tank (48 gallons) and the pick-up
tube was replaced last year to go further down into the tank so neither
the fuel level or pick-up tube level can be issues. I also added some
Stan-dyne (?) when I last filled the tank earlier this year.
The Neuse River was almost flat since we had only a 5 knot breeze so I
doubt that it was 'stirred up' crud from the tank.
Haven't replaced the fuel filter between the tank and the engine or the
engine mounted one this season (did it last year) so that is my first
chore
since IMHO it looks like a fuel issue or an air in the fuel line issue.
I also will check all the clamps that are used to seal the fuel line
from the tank to the engine.
Does the list have any other suggestions/ideas besides what I listed?
TIA,
