Vauxhall Astra engine management and alternator lights

Car: Vauxhall Astra
Variant: comfort estate
Model Year: 2002
Categories: Electrics, ECU, Warnings & Lights
The alternator and engine management lights come on now and again. When on, the rev counter drops to zero and the car slows down. After a while the lights go out and all is well again.If I stop and try the pedel down trick, there is no information, also my local garage put their diagnostic machine on it and got no information. Any ideas please.

Might be worthwhile getting alternator output tested and alternator socket / wiring .
