  There is more fuel pressure when the tank is full. Look for partial blockage, screens, filters etc.

  Welcome Dean ,
  
  Totally agree.
  
  You may have to remove the sediment bowl assembly to check the in-tank strainer.
  
  There is also a mini-strainer in the lift pump suction banjo bolt.
  
  This symptom also suggests the onset of diesel bug contamination. See if there is a dark brown or black sludge anywhere in the fuel system.
