Engine Cuting Out !

[so called]

So later last year I had my Speedsix rebuilt.
All seemed well but earlier this year, I notice a couple of issues.
First, a missfire.
Second, the three lights on the right side dash gauge would flash and at the same time the car would stutter.

The car went back for a check up where they found water ingress around the spark plugs.
After that corrction, the stutter still existedsuch that the workshop checked earth bonds, alternator connections etc.
They didn't realy find any issues apart from the alternator connections being, maybe, not tight enough.
The problem still remains and I'm wondering if anyone else has suffered similar.

I'm sure its a loose connection somewhere ???

I'd hazard a guess at the alternator itself or perhaps the main fuse.
