Hi scope/multimeter the fuel rail pressure sensor check voltage when cutting out at 1500 rpm.
If the FPS looses its ground reference from the ECU or if it is unplugged/ dodgy connection the ECU sees 5v and presumes the fuel pressure is sky high. The ECU inturn drives the inlet metering valve shut= no fuel pressure.

There is a modified wiring loom and sensor for this particular fault but, I've sorted 4 out by just cleaning and squeezing terminals for a better connection.
