ok this has happend a few times, but very speratic, yesturday i drove my car (87 iroc 350 tpi) all around and it drove awesome no problems, i parked it in the driveway, and went to start it in the morning and it started rev'ed up and then just died and it wont stay lit unless i keep my foot on the gas, it just wont idle. it almost sounds like it is miss firing. and it doenst seem to throw any codes but ill have to get tomorrow. the thing that is weird is it drove perfectly the day before and now it just wont run at all. anyone have this problem before?

 

MAF relays, f/p or ign module. I'd start with the relays.
