Hi there I have got a problem with my 1.0l '04 Lupo with 67000 on the clock, I seem to be losing all power to the car rather randomly. I will get a check engine light and the EPC light on my dash momentarily then the engine stops the clocks and radio turn off. the car is without electrical power for around a minute then switches back on.There are no noises coming from the engine before this happens. I have had a unsuccessful search online and my only thought is the alternator. Any help or ideas would be greatly appreciated
