it is LT1,someone is selling it and then then mentioned this issue,saying they had almost whole computer system replaced,and still does it,so I was seeing if it could possibly be an easy inexspensive fix or stay clear of it being this would be our first vette

It could be a few items. You would have to duplicate the problem and do some testing while it won't start. Some of the suspects are the ignition control module, coil, ecm and optispark distributor. Here's a thread to read to give you an idea, https://www.corvetteforum.com/forums...-and-dies.html

Confirm by checking spark, ignition pulse and fuel pressure. How many miles?

92 is the un-vented Optispark.
