Rallye starting issue

[tarmac terror]

So, got this sorted....
Replaced the starter for a TD variety and all is good in the world again.


However.

Prior to the starter quitting I had an issue where I would be driving along and the car would suddenly lose power gradually and then cut out. Dash lights, radio etc were unaffected. Quickly turning it off and restarting would have it up and running again until the next time (usually every 5-10mins).
I have changed the cat, lambda, MAP, ECS, IAV, Crank sensor to no avail.....


Any ideas before I go out and buy a Lexia3?
