Solved this problem on my 2005 GV. After a massive exchange and cleanup of sensors, filters, fuel filter housing etc. the remaining cause had to be the fuel pump itself. Handed it over to a mechanic who confirmed that two out of three return valves were stuck. This led to a drop in fuel pressure or lack of fuel to the injectors as only 1/3 of the diesel could pass. Replaced the small steel balls of the right size and problem fixed. These balls came in a small bag and was easily fitted. These balls get worn out over the years. I see a lot of frustrated GV owners out there, like myself. Great car except for all that needs fixing all the time A lot of interesting ideas in this forum, but don't get carried away. Engine cutting out at acceleration must be fuel starvation. Take it from there. Check the moving parts first....they always wear out first...
