has anyone ever had an issue with their car randomly shutting off?
There does not seem to be a rhyme or reason but it will literally shut off completely at random, engine and all electronics. I don't believe it is anything from vibration because i have had it happen to me while cruising down the highway and also while sitting at a redlight in neutral. The anti theft light doesn't come on so i wouldn't think its the ignition switch but i could be wrong. i happened to catch it happen this morning while doing a datalog so i will attach the log and maybe someone could see something that im not or maybe someone has come across this.

It looks like the battery voltage started dropping right before it stopped recording.

Yea I noticed that too. It stopped recording because that's when everything shut off. Its crazy because the rest of the time the voltage is perfect. And it will immediately start back up. When it happens on the highway i just have to press the clutch and start it and keep moving. I just put that battery in less than a year ago. All cables are tight and I cleaned up the ground surface and made sure it was secur while installing my CAI. This has happened a couple of times when I still had the original Z3 engine in it as well so I know its not the engine itself.

It may be an alternator issue

Thanks for replying. After really looking at the terminal connections, the positive connector had a crack in it. So although it was tight, with the right amount of twist to it, it would loosen up some. New ones will be delivered tomorrow. Thanks again
