Alrighty folks

1981 245 K-Jet B21F (California). Recently had the head reconditioned, has run pretty good since then. Always has had a shaky idle, calmed somewhat by the head rebuild. Now this evening on the way home from work, on the freeway, the car starts to buck and cut out. Coast to the side, no idle, all dash idiot lights on. Won't start. Turns right over, but no start. I try the spare fuel pump relay, no go. I jump the fuel pump fuses, no go. Eventually I push and prod and fiddle with IAC connector, Frequency valve connector, and it starts up and runs 'normal' that is with a bit of a shaky idle, but good acceleration and such. So I make it home and have a couple beers. I'm thinking the Frequency valve is the culprit, or the electrical connection, because that was the last thing I fiddled with before it ran again. So I clean the electrical connections on the IAC and the Frequency valve. Car fires up and idles. Frequency valve is buzzing real nice. Then the idle falters and dies. Now it won't start.

Soooooooooo....

I figure the thing to do would be to tear the whole engine compartment apart, replace the engine wire harness, etc, but I need this car for commuting. Any suggestions as to what my issue(s) might be?

Thanks guys, I need help
