Air getting into the fuel line?
I have a similar problem with mine, same vintage. It starts okay, but
cuts out two blocks from home, always at the same spot. Starts again
without problems. Pehaps an air bubble in the diesel line..
Otherwise going well for a ten-year old! No more problems since Isuzu
(via Opel in this case) agreed to replace the fuel injectors about 6
months ago. Whats your mileage?
