Hi

Thanks for letting me join

I have just purchased at 2009 850d gator with 900 hours on the clock.

I have a issue with it where after approximately 5 minutes of running the engine cuts out and comes to a stop. The cooling fans are going. Once the fans stop running after 5 seconds it will start and run for another 2 minutes and do the same.
If you try to start whilst the fan is going it will just cut out again.

I have checked the thermostat is opening ok. All pipes to and from the radiator are hot. Radiator is hot all over. And full of green fluid.

I have checked the fuel filter and is clean.

it does have a electric pump on top of the rocker cover that I think has been put on.

have done as much as I can and would appreciate any help

Thanks add

Check the fuel pickup filter in the tank, fine gauze screen on the bottom of it that could be blocked, seems unusual that someone has added the electric lift pump on a machine with quite low hours...
Remove the seat and you should be able to pry the plastic cover enough to gain access to the pickup and return lines, if not a small cut of the vertical section of the plastic will help, also check for tank vent blockages

Hi thanks for your reply

I found the problem last night

it was a broken earth lead and when the fans cut in was pulling to much power for the earth that was on there

thanks
