Cliff,
My bet is an electrical problem. Swap out the wire on #5 to see if the
wire is a problem. Next, swap out the plug. If these measures don't
work, check the distributor cap.
If you still have the problem, it may be time to pull the valve cover off
and see that the valves are moving.
Let us know.
