Get the clutch pressure plate and friction plate changed, and have the flywheel turned and balanced, or replaced.
Thanx ss-traveller. Actually I was thinking on the same thing a day ago as I got the exact same diagnosis from a mechanic guy when he listened to the symptoms. His take was that this can't be an electrical/ignition problem since the problem never occurs at standstill or startup. Never. No hiccup, no starting problem, no shivering, nothing. I'll look into it ASAP.
