under the plug cover there are 2 or 3 earths
i advise you to clean those up and the bolts and washers and the earth that goes from the bulkhead to the back of the engine.
I noticed that the ME7 engine relies heavily on having good earths for the individual coils.
Dont keep chopping and changing sensors willy nilly as its very costly.
Go for the simple things 1st.
put a voltage meter across the earths and see that your getting full voltage there.
It sounds like something is breaking contact when you come to a stop so make sure you check all the earths and also check that all the plugs and connectors are clipped in properly.
if all that fails then it could well be the ETS unit.
Have a look what colour sticker is on the ETS unit.
If its a white sticker it is the original one and if its a yellow sticker its a recon unit.
If the car has had the factory ETS software upgrade it is alot harder for the ets light to come on.
The ETS has 2 potentiometers either side that consist of "fingers" on a carbon track.
if the throttle is returning down to a certain rpm where the carbon track is worn it can cut out but only seen this once before on a cabriolet 2001 car with 67k miles.
good luck with the earths and i hope it solves the problem for you.
let us know how you get on
