I've been having bit of a puzzling issue with my G35 coupe (2005, 6mt).

This started Monday after I pulled over to gas up. When I got back into my car to start it all lights came on as usual but when I turned the key to actually start the engine all that happened was it clicked once than all electrical power was lost.

A few minutes later a couple lights would come back in (but very dim) and the key remote can unlock/lock the car. I got a jump from someone and the car started up right away. I drove home (Vancouver - Coquitlam) fine.

The next morning, the same issue happened again. Turn key to start, click sound, all electric power lost. Jumping the car again started it immediately. After I got to work, I turned off my car and then started it again with no problems.

Leaving work yesterday I had no problems starting and made it home fine. When I got home I turned the car off but the issue happened again when I tried starting it.

I required another jump start today morning, but this afternoon the car started up perfectly fine after being parked for a few hours at work (I tried about 4-5 times in a row: start, run for a minute, turn off).

The battery is still fairly new (installed September last year) and there are no aftermarket stereo accessories.

A similar issue was happening last year but stopped until this week when the new battery was installed.

Anyone have any idea on what could be causing it?

Edit: Had no issues yesterday after getting a jump in the morning. Started up fine after work and when I got home. I installed a new battery just in case and will wait and see if the issue persists.
