Test the icm and don't forget the thermal grease. Look at the conections on the temp sensor on the water pump.

Welcome to the forum.

When it dies, did you check for spark off the coil?
You really need a fuel pressure gauge so you can monitor the pressure and see if it is proper.

The intake air sensor (If that is what you mean in the bellows) is probably not the no start problem.

I know my response isnt from a corvette but it bears mentioning. I worked on a car once that would die when driving over a railroad crossing in one direction only. Was really a crazy bug. Found the problem when lifting the car with a hoist and the lights on. When the last tire left the ground the headlights would go out.
Bad ground to the frame so the distribution block under the dash would float high and the ignition circuit cut out. Once i ran a new ground to the distribution block all was good. It wad one of the craziest electrical problems i ever had to find. I was too focused on the distributor/coil and other parts. Everything checked out as long as the car sat on the ground
