My 94 z28 quit on me. I dont know what is wrong but I have plenty of gas and enough battery to be able to start the car. Yesterday, I started it and had felt it idling just a LITTLE bit of a miss. So yesterday, its sitting in my driveway running in park and it dies. No sputtering or chugging to death...just stops running. So i tried to crank it up and it wont. I pressed the gas all the way down and it turned over.
It ran fine after that but still with a little miss, barely noticeable. Today, I get in it and drive just less than a mile and im driving when it dies. Again, no sputtering, just dies. It desperatly tries to turn over and at times you can tell it ignites in a cylinder or two but wont stay cranked. I pull to the side of the road. Wait 15 mins and still wont crank. So I called AAA and the guy came about an hour later. He couldnt get it to start. So we towed it about 2 miles, let it off the truck. And it cranked. I didnt drive it away fearing that this would happen again.

Could it be fuel pump, fuel filter, spark plug wires, distributor?

Should I first check fuel pressure?

When you say it won't "crank", that means the mtotor doesn't move at all? If so, that would rule out any fuel problem and make it electrical.

I've heard that the optispark system on the LT1 is a problem source (I've never had one though). Perhaps that is going bad on you?

I have heard the same thing, one of my friends in Florida had an LT1 and his opti-spark kept taking a crap for no reason and sounds kinda like what yours is doing. Hope you can figure out the problem.
