possibly a vacumm leak/ hose deteriorated/ at an idle,as it dies-do you hear an audible hiss-sucking noise(vacumm leak)
'if' you can keep it running from under the hood-try to spray brake clean,with the straw that comes with the can around,!!STAY AWAY FROM DIST CAP!! if it has one.if rpm picks up you are close to a leak.
might just try -disconnect battery for a min.& reconect

i am a 'ford' tech,so not too familiar with the g.m. set up.
there has to be a way for the pcm to control idle speed.
possibly a malfunction.
if you try, can you hold it at an idle speed,or does it die when rpm drops below say 1500 rpm(avery high idle)
if you can 'make' it idle i would think along the line of the devic that controls idle speed.
if it dies below the high idle speed-i still am leaning to a vacumm leak.
