firing problems

What would cause the cylinders 2-3 to stop firing when the motor gets warmed up to operating temp?
just installed Brand new plugs, getting fire on 1-4 constant, changed around wires until I got spark on 2-3 then refired it, it ran awsome until it warmed up then PTTTTHHH! nothing on 2-3 again.

its really getting on my nerves.

sounds like a bad coil. check for power at the coil after they stop running and make sure all the conections are clean.

coils are fine, found out that the wires got chewed at the ignition plate.
now im completely screwed as I sold my second parts motor and have no funds, also my Soldering iron conveniently walked away.

so, i just hope I can find a soldering iron somewhere to repair the lines.

well, if someone happens to have a spare they wouldnt mind parting with U2U me please. I cant fix this one.

its the electronic ignition pickup plate.
