Re: 99 Lumina LTZ stalling issues

The fuel pressure at the fuel rail is 43 psi. Goes up to 50 psi when running if I remove the vacuum to the fuel pressure regulator; goes back down to 43 when I put it back on. Goes up by about 5 psi temporarily when you goose the engine.

Pressure bleeds off to 30 psi after 10 minutes of engine/ignition off and seems to hold there.

Yes, if I drive it around and stop for a while, then it stalls on restart unless given some throttle to about 1000-1500 rpm for a minute or two, then will be able to settle down into a smooth idle at about 730 rpm.

It may start right up if I try to start it immediately with no stalling. After half an hour, it definitely will stall on restart.
