I had that problem last week................it was my "Ignition cylinder" It sounds like your problem is different though. But check out my thread. Do a search on "My car will not start..........Help"

I had the same problem and in my case it was the battery. A straight swap for an Optima Red Top and I was back on the road.
Mine was a year old and had done 8k miles when it died.
If your battery is the original AC Delco, I'd bet money thats the culprit.
BTW, if you fill out your profile members can offer advice specific to your car.

Had the same thing happen Monday. Better check that battery and FAST. My positive post came completeky out of the battery, leaked acid, and now that I got it cleaned up, I'm having HVAC issues. Probably unrelated to the acid as it wasn't there long enough to cause any real damage, but who knows.
Check that battery!

It more than likely your battery. You'll need a new one. Probably about $80. for a AC-Delco Pro series if you want OEM similar.
Expect all kinds of codes to have been set because of this. If you swap out the battery be sure to clear the codes, that should reset all the warnings. Low power on the PCM makes it very upset! Hope you aren't affected by column lock, low voltage will cause it to show its ugly head unless you've had it bypassed or not affected by it.
Good luck. If you need help with the DTC ask I'll post up the steps.
