sounds like you need new leads, they dont last forever, replace them 1 at a time

look at engine running in the dark for any sparks

usually if u replace one lead you may as well replace them all then you dont loose track on what leads are new/old.
While your doing leads you may as well check plugs give em a clean. Or replace them as well :P
Cracked lead will cause it to earth out on the block/head and not fire in the cylinder
