Intermittent Starting Problem-02 WS6 M6 Help!-The car has done it twice in the last two days without warning. It's like the battery has been removed from the car. No dings, no lights, no warning lights, no cranking, no locks, no windows, no alarm...Nothing! Thought it might have a short so I checked the battery with a meter to see if it's dead = 12.41 Volts. The first time it did it, there was a clicking noise coming from the Ignition Relay. I disconnected the battery and waited a few minutes. I re-connected the battery and it started, but idled rough. The relay had stopped chattering. Turned the car off and back on and it idled fine. Drove a few miles to an advance auto and bought a new ignition relay and it was fine for 2 days.
Last night it did the same thing. This time the relay didn't chatter. Still 12.4V at the battery. Disconnected/Reconnected the battery and it started, but idled rough. Turned it off and back on and it idled fine. The 50A ignition fuse is okay.
The car only has 48,000 miles.
The only thing I've done to the car electrically is a skip shift eliminator, a peripheral isimple ipod interface kit, and added a Susquehenna Motorsports Headlight relay kit for the 150mm Bosch Headlight Conversion. It draws power from the battery and uses relays to turn the original headlight wiring into a control circuit. No cutting or splicing...It's plug n play and seems to be working fine.
My wife said that a few times over the last 2 or 3 months she's noticed that when starting the car there will be a slight hesitation before the starter engages.
It's got me bewildered. Anybody encountered this or have an idea of what the problem could be.

Since you said you had no lights are you saying that with the key off and light switch on they are not on?If this is happening then next time with light switch on check voltage at the bat and see if it reads 12v if it doesn't you have a flaky bat.If it reads 12v then check your pos and neg cables as one or the other maybe screwed then see if moving them brings the lights back on then you have a path to chase down.

The next time it does it I will try that.
