I agree with John, is there possibly some fuel incompatibility?

Some questions:
Where is the pump located? Too hot? Getting bumped? Other?
Could there be a voltage issue? I canít imagine low voltage causing your problem.
You donít show a filter. Where is it?
Is there appropriate continuous fuel flow in the main circuit (your heavy line in diagram)? With 4 PSI drop across the mechanical pump I would think so.
What is the outlet (return) fitting? As I recall that determined the fuel pressure in a stock configuration. Is that still in place?

You might look at plavan post and consider if something there might be an influence. FYI- Fuel Safe Defects- What you need to know.(Long)

Best,
Grady
