High. I have a 944 S2 1989 which has developed a small problem, about 45 seconds after starting and when I come to set off for a split second the car looses all power, even the radio goes dead.It is for a split second because the car doesn't stall. Everything is then fine and it wont do it again. It is somewhat disconcerting because the whole car comes to a dead halt (momentarily) and I could end up with someone going into the back of me.
This happens about one in every 4 times I start the car.I have checked the battery and alternator leads and all is fine. Does anyone have any ideas what it might be?
Cheers

Worth pulling fuses & relays one at a time & cleaning reseating. Not sure why it only does it once, otherwise I'd be looking at ignition switch.
