what pump are you using and is it hard wired?

Retime your cam angle sensor.

Buy a Walbro 255 and hardwire it.

Check for fuel leaks

It's normal for the fuel pressure to drop off when you stop cranking. The regulator is at the outlet of the rail and there's nothing keeping the fuel pressure from back flowing to the tank from the rail.
