and sometimes it will stop as if it is running out of petrol, checked the fuel filter and the pressure and the injectors.

Check fuel tank breather pipe is not blocked with dirt. Creates a vacuum in the tank and stops fuel from flowing.

If the car stops as you're driving, stop and open the fuel cap. If there's a vacuum built up you'll hear the influx of air as you remove the cap.

Unlikely to be this if its not starting from cold though.
