Sounds like a faulty fuel pressure regulator, or possibly the MAF sensor.

Have you checked the cam sensor? Also does that vehicle have a "throttle position sensor"? Some cars use both MAP and MAF sensors, not sure about your particular vehicle but if it is one of those, cleaning the MAF wouldn't hurt. Good luck.

Does this thing have a throttle body that looks like a computer-controlled carburetor?

If so, start motor and verify that it behaves irratically and then stalls.

then, spray WD-40 liberally around base of throttle body where tb meets intake manifold.

Start motor...

Does the problem go away, at least whilst for a little while?

Yes?

You gotta vacuum leak. Replace gasket under TB and tighten bolts to factory spec.

Check EGR valve. Also check all injector pulses with NOID light especially when vehicle is stumbling. It may be computer related. Get back to me if you need more help. Good Luck
