Well maintained P38 4.0 HSE with recent oil change. Just had above issues occur along with fuel warning light on with half a tank of fuel. Tried selecting neutral whist driving it just says slow down.... The engine is now struggling get too fifty mph, I think its in limp mode.... Although, had recent reverse gear selection challenge. Selector on side of box was tightened up by garage that fitted new exhaust.

Considering purchasing nano com evo to get to route cause.... unless someone local can help or advise otherwise?

Check the Technical Section on how to test if the lift-pump is delivering enough fuel. You bridge a relay and should get a certain amount in a certain time.
