92 Prostar 190 with 351 running rough question

92 Prostar with a 351 HO that I'm getting out for the first time this spring. Worked on it yesterday changing fluids and running in driveway and everything was great. Ran it for 15 minutes or so to get it up to temperature and again when I was done and everything worked well.

Today before changing plugs and doing a couple more finishing touches it is not running well. Starts quickly and runs as long as you give it gas. If you try to hold any RPM or idle it won't stay running. Pulled the fuel filter in the tank (On the end of the fuel line) and cleaned it. Changed the plugs and still no progress.

Looking for the next things I should check?
