Need help!!!! Fuel Issues

[Stimsde30]

Hey guys I have found a few threads that display similar issues but I can't seem to find any that match all of them and I'm kinda stuck. Here are all the symptoms of my car before it stopped working.
- the car ran fine for about 30 min and then started to sputter eventually after a little while.
- once car finally cut out it took about 15 min of cooling down before it started and idled correctly. Then after about 10 min the problem came back.

This is when I replaced the fuel pump, the injectors and the ignition coil
But the problem got progressively worse. A few days ago I drove out and the car was running well ( because it hadn't warmed up yet) and I took a hard right turn and the car sputtered once and then the engine shut off. I have not had any luck starting the motor ever since. I did I fuel pressure test and when I crank it it get up to about 40 psi but after I stop it quickly goes back to 0.
I'd really love to get my girl back on the road again so if you guys can help me get to the problem I would appreciate it. Thanks

Pull the vacuum line (thin black rubber hose) off your fuel pressure regulator and crank the engine, do you see any fuel coming out of there ?

If the FPR diaphragm fails fuel will flow through that hose into the inlet manifold and choke the engine till it dies. This will also account for the rapid drop in fuel pressure.
