I had exactly the same problems with my 98 ST2 last summer. I ended up replacing the Regulator and fitting an uprated ignition wiring kit from Powerlet (www.powerletproducts.com), I think you can order them from the UK as well from here (http://www.blue-job.co.uk/).
It was very simple to fit and the delivery from the USA was very quick. It's worked fine ever since (Fingers and toes crossed, touching lots of wood and things)

When I had my 98 ST2 in 2003 (so well outside the warranty), I had a new altenator, rectifier and battery fitted at WM Snells and all paid for by Duacti. There was a recall on these bikes so it may be worth checking yours has been done. Call Ducati UK with the frame number and they should be able to tell you.

Great stuff - there's lots of useful info there for me to have a go at.
Thanks very much to you all.

Just in case it is the charging system, here is a fault finding chart that I've found useful in the past:

Now here's a thing:

I've just been on to Ducati UK and even managed to talk to a real person after a long time.
My bike - which is now 8 years old - is due 3 recalls through any official dealership. (Thanks to Chris Q for that brainwave).
These are:

1 Replacement generator (and possibly regulator/rectifier)
2 Frame check (apparently there's a weak point but he wouldn't say where)
3 Front sprocket plate check. The originals were mild steel, not hardened steel, and they wore away and then the front sprocket fell off.
The original (soft) plates were gold. The replacement hardened ones are black, so you can easily check if any of this applies to you.

Ducati UK are still happy to pay for all this work regardless of age.

So - just goes to show that if you don't ask you don't get. But also fairly scary that many bikes similar to mine may never have had these faults rectified. My bike was owned by the same guy from new until last year. He never moved house, but he was never contacted over any of these recalls.

I hope some other people out there benfit from any of this, and many thanks for everyones' replies to my original post.
