Ok heres the latest on my 1992 G20 conversion van. Replaced following..
New plugs/wires/cap/rotor
Fuel pump/filter/start relay
Switched fuel injectors- one wasnt doing so good.
TPS sensor.
EGR solenoid
Map sensor
O2 sensor twice now.
couple vacuum lines.
ICM
Ignition coil
But yet I have same issue....after warm or at operating temp..let it sit for awhile...go to start, it will fire up for a few seconds then die...not every time but almost...i have noticed that if I hold gas pedal all the way down it attempts to start quicker...the last code I had was MAP sensor..which I replaced today, before was O2, had that one on a regular basis, even though its new...
I dont really know what else to check other than fuel pressure however dont have the guage yet...next is mechanic for me...

You describe the symptoms of a bad or leaking fuel pressure regulator perfectly
