I thought it would be helpful to relate my recent experience to everyone in the community.
My Mk111 has all the appropriate upgrades and generally behaves really well, it starts on the button and performs like a well sorted machine.
However over the last few weeks starting has deteriorated into a hit and miss affair, until one day when it finally fired up, it was running so rough, that I wasn't going to risk going out on it. During the starting process it had the unusual symptom of after multiple attempts, the entire electrical system dying for 3-5 seconds, and then coming back to life, ready for another attempt.
I was determined to find the issue and spoke with a wise friend and he said that based on his experience, it would be worthwhile examining the main fuse first.
So I put the meter on it and found 12.6 volts going in and 9.4 volts coming out. On opening it up, I found that a heavy layer of crustiness had formed around the mating surfaces, impeding the current. I run a Mk4 boyer, so this would have been right on the edge of its cut off point.
With a new fuse and holder installed, it now is back to starting on a touch of the button. I am grateful for this point in the right direction, as otherwise I would have spent a lot of time trying to track down the issue.
Hopefully this tale may help someone else to fault find efficiently.
