2011 6.7 diesel warnings

[lifwghts]

I was driving all day today 1/2 fuel fresh filters
And noticed warning "reduced power"
And then "low fuel pressure "
I have noticed that my fuel pump has been
Very loud after Ford factory changed both
Fuel filters and now this ; taking to dealer
Tomorrow

Full DEF and 1/2 tank fuel and was driving
All day long

2011 F250 39k miles
Any ideas ?

Thank you
