This turning the key on and off, which fixes things, and the occasional rough idle that myteriously smooths out at the snap of your fingers, makes me think CDI ignition module. Or, could be as simple as a loose coil wire, or other loose stuff (man, if that isn't vague....).

Also look at your fuel pump connections up at the fuse box. Unscrew and pull the wires from the fuse mounting points, clean them well, reinstall and torque down. Clean the fuse and it's contacts, pull the red pump relay and clean the pins and expand them slightly for a nice tight fit when plugged back into the socket.

The next time it does this you need to do some diagnostics to determine spark or fuel related. Are the pumps runnning (key on, pull the connector plug back behind the metering plate in the fuel head). They should run at that point. If not, that will tell part of the story.

There's a whole littany of stuff to look at.
