'90 Cutlass Supreme 3100 PFI

[mccabet at mediaone.net]

I need some help diagnosing a problem with a '90 Cutlass Supreme with
the 3100 PFi engine.  The scenerio goes like this:

Engine starts and runs when cold.  It will re-start as long as you don't
let it sit for a few minutes.

Once it has sat, the engine will start and then promptly die. 
Depressing Gas pedal makes it worse (Dies quicker). 

Checked fuel pressure - 42PSI Key On Engine Running, 44 Key On Engine
Off.

Scantool shows no error codes in system.

TPS checks good with no fluctuations noted.

I know chrysler systems better than any other so I am lost on this one. 
A shop claimed the injectors was bad a quoted $1200 to fix.  I don't
think it is injector related since the engine will start and run when
cold.  By The Way, the engine will keep running and will even restart as
long as you don't let it sit.


Any help appreciated.

Thank You!
