Steve, Actually, I don't think those symptoms are the classic "Vanagon Syndrome" that is due to a bad spot in the AFM tracks. That happens at steady speed highway driving when the head of meter sits over the worn spot steadily and therefore give erratic signals to the ECU causing it to cut out. If your problem happens at idle, it is most likely something else. Attached is a zipped set of files written by list member Mark Keller that together provide for a systematic diagnosis of Fuel Injection system problem that impair engine performance. Also included is zipped set of files by list member Dennis Haynes about the fuel injection system primarily focusing on the O2 sensor and how to tell if it is causing your problems. Regardless of what I think, these files will allow you to precede systematically. You have already gotten a good start by checking grounds. Many times a bad ground or two are the source of a problem something like this. Did you check the grounds at the battery and from the transmission to the frame, fuel pump to frame? On top of all of that, try making sure that the connection from the Hall sender to the side of the distributor is nice and tight. Just a hunch, but it takes 5 seconds to try it. Also check idle stabilizer in the space behind the right rear taillight assembly.
