Engine looses power temporarily

[privatealpha]

Motor is a 4agze turbo running Adaptronic ECU.

While driving, car looses power, then the tacho flickers up to 3-4000rpm, and just before it stalls engine power comes back and all is well.

Has been happening for the past week.

Sometimes power is lost for less than half a second, and only recently I lost power for nearly 3 seconds.
Its weird that the tacho flickers to 4000rpm when clearly it is dieing.

Any ideas?

start by checking that all your grounds are secure and clean. i had problems in my ae92 levin with 4AGZE till i found the earth strap to the head was loose

Yea ill go check around.
At first I thought it might be the fuel pump but that wouldnt cause the tacho to flicker.
Could be the ignitors?

Ill give a good looking over with the grounds.

And the engine is a AE92 Map 4agze.
