Default Crossfire injection

My 1982 Corvette has a problem as when I start it up it runs fine and idles OK but after a few minutes it starts dumping fuel and dies and it does it on both injectors, also it has not vacuum at idle out of either injector. Stumped as to what is wrong

Sounds like the gaskets in the throttle bodies is leaking fuel. Have you read the data stream with a scanner?

No I do not have a scanner, so you think the throttle bodies need rebuilt

I don't know because I'm not there. What I do know that a leaky TBI gasket will cause exactly what you were describing. I mentioned the scanner because it's important to see if the ECM is receiving the correct feedback from the sensors, namely the CTS. I wouldn't rule out a vacuum leak either.
