could it be the Exhaust Recirculation Valve ?
The engine management light comes on and Engine cuts out or lacks power then it clears engine management light stays on and cars fine.

It's probably the air mass flow meter senser.

I had the same symptoms - lack of power, hesitancy, and reduced economy. Reading around I found it's the most likely cause. Took to a garage to check, their computer linked upto the car's cpu agreed straight away.

Item replaced, no probs since. Like a new car. Ebay has loads for sale cheap, then take it and car to garage, and let them fix it if you want. Job done.
