Moisture, bad / intermittant earth are my best guess's off the top of my head.

Sounds like it may have been damp. Is it carb or injection? Sticky injector cause similar symptoms?

8v vauxhall engines have a nasty habbit of destroying the plug lead on number 3 cylinder (When Driven hard) ive had that happen many times if the leads are not very old try wraping them in inslation tape also check the plugs if your have a cylinder down the plug or plugs will be damp after turning the engine over on a carb models

If you only had issues with no. 3 you aren't driving it hard enough, lol.
