Fuel temp sensor port is upstream of fuel pressure regulator thus should read 6-7 bar. As engine takes fuel this should drop a bit but not below 5.5-6 bar at full boost.

Two options, either FPR is fubar (not holding pressure) or fuel pump not delivering enough volume as to keep pressure up (partially plugged or fubar).
