This sounds like the anti theft security system failing. Very common on GM vehicles, especially 80's Corvettes. The system was originally designed with a starter disable system if the security key was not correct. (or if it was being stolen) Corvette and Cadillac started using a fuel disable system since people would just the starter to steal them. The symptoms are exactly what you describe. Vehicle starts and runs for 1-5 seconds and then dies. It is actually turning off the fuel injectors. You may even see the security light turn on afterwards.
