As of last night my 2010 G37 coupe 7AT has stalled randomly 3 times. At the time of stall all the dash lights come on, radio and lights turn off, and the car subsequently turns back on about 2 seconds later. All 3 stalls occurred while starting from a stop and between 1500 rpm and 3500 rpm at 15 to 25 mph.

Mods: Typhoon KN intakes, Test pipes, mid pipe, y pipe, axle back, lowering springs. Battery hasnt been changed since I've owned the car. 46k miles to 92k miles. 1 year and 4 months. No previous damage. No new codes besides for the o2 sensor codes my test pipes have been throwing for the past 6 months.

have you cleaned your throttle bodies? i had some rough idle and start and stall issues when they were really dirty. there is a DIY on here.

do you have a tune?

What's the relay housing called? IPDM or some such? Could be that, and not inexpensive to fix.

Sounds like it's your battery.

Bingo! Found this out earlier today when I couldn't start her up at the gas station after having just driven there. Corrosion on the terminals and connections. Don't know why I didn't think to check earlier though. Thank you guys for answering!
