I have had similar mysterious cutting out issues on an na and a turbo which I eventually traced to the ecu. One would run OK for a while and then just decide to cut out in the worst possible place, like the middle of a busy roundabout. The other had a habit of dying when you dropped the revs at a junction and pushed the clutch in.
The na ECU looked fine with no signs of a leaking capacitor, but we eventually found it was turning off the injectors after a few mins, so there was obviously some sort of fault in there.
When I opened up the turbo ecu I found two of the capacitors had started to leak and damage the tracks. In this case the engine management light also came on and at one point fancied itself as disco lighting.
Changing ecu in both cars sorted the issues. But both cars were rev 2, and leaking capacitors on that rev does seem to be a common issue.
Unfortunately there are so many things that could cause this, so this may not your issue, but given how easy it is to whip the cover off the ecu, it's got to be worth taking a quick look for any signs of leaking caps.
