My 1989 SC sometimes runs and other times wont start. when hot no start. when cold like sitting overnight it will start and run great then dies when normal operating temperature is reached.
 
Maybe a massive vacuum leak. Will only run when it is being richened up for cold start.

How much vacuum when it is running cold?
 
I found a broken vacuum line contributing to a vacuum leak. I will check the temp sensor for the ECC and EDIS. Thanx for the input. This has me stumped.
