Yea one mechanic told me I need a whole new eis another said it is my transmission. I know they hooked it up to the star machine but I don't think they found anything definitive.

Well it is unlikely to be something like a neutral safety switch - the starter shouldn't operate. I'm not sure if something wrong with the electronic brain on an automatic transmission would stop an engine from starting or encourage it to shut down. Wait for others to chime in on that.

As the response from the mechanics isn't especially helpful I'd start by cleaning electrical contacts and checking for damaged wiring.

It is possible to get little data loggers that attach to diagnostic ports so you get a better idea of what is going on rather than just a snapshot in time.
