1979 Trans Am ENGINE DIES On ACCELERATION 6.6 liter

I have just put my 1979 Trans Am Back on the road, It's been parked since 1996. Has 75,000 miles on it. I just had a local GM dealership give it a tune-up. I picked it up and it sounded very smooth but as I left, It would die about every quarter mile on acceleration and the engine would cough then stop. I could start it back up pretty quick but would only go a little ways and die again? They put a new rotor, plugs, fuel filter, air cleaner. This is the problem I took it into them for in the first place. Any suggestions? Is this the right place to take a car of that year? It sat for 11 years covered in a polebarn with cement floor, I would start it a couple times a year and take it for a quick run down the road each summer and fall.

They switched out the control module and that was not the problem, the problem happens as the car starts to warm up. They thought it might be the inline fuel fillter but the new one is still clean. They put the car on a scope and think it's in the iginition system somehow.

Does the car have an EGR setup, if so remove the vacuum line from the diaphram and take the car for a crack down the road to see if its better.
