1990 Cadillac EL Dorado ECM?

After running for a few minutes the engine dies. If you immediately try to restart, I does not start. If you cycle the off and on and then it starts. I pulled many codes from a 1990 El Dorado and they seem random. Are these symptoms of a bad ECM?

Check battery first for condition including load test. Autoparts do for free.

Clear all the codes by disconnecting the battery for about a minute and then start out fresh no sense looking up codes tha tare in history as they may not be correct anyhow.
