Engine stalling

[dalenruth]

Hi everyone
I have a T25 with a 2.0 Aircooled engine which has developed an issue;

It runs for a few miles then suddenly loses power and stalls. Initially it started again but then stalls after a few yards. Im sure it isnt lack of fuel as it has twin carbs and doesnt judder like you would expect with fuel starvation. It just simply cuts out. Im guessing it will be electrical but i really dont know where to start. Has anyone suffered with a similar issue?
Yesterday it started and ticked over as sweet as anything but after 10 minutes it cut out and wouldnt fire. I removed a plug and found it wasnt sparking.
Many thanks
Dale

^ What these guys have already said ^

I had a similar sounding problem.

I replaced the Ignition Amplifier with a generous helping of heatsink compound, that seemed to sort it.
