Ford Kuga power loss

I bought a used (2009 model) Ford Kuga diesel about six months ago. Since then, I've had to take it back to the dealer several times as the power intermittently cuts out. The car is still under warranty and the dealer has replaced the air box and inspected the mechanical parts, but the issue continues. Can you offer any advice?

Might be the mass airflow sensor, or might be a bad connection inside a multipin connecting block that has suffered some moisture ingress.
