As far as I'm aware, spitting back could be due to a lean mixture and/or timing issue. Intermittent problems are always 'fun' to track down.... You seem to have ruled out the most likely suspects but not the RPM and timing sensors as Jools suggests. Might be worth checking air gaps and swapping them around (or trying alternatives if available) and see what happens?

Definitely sounds like a firing issue rather than a fuel issue.
Start at the beginning and work your way through: timing > ecu/cdi > coils > leads > plugs
