My wife and I were driving back to Arizona from California 3 days ago in our G35 sedan when something strange happened. I was driving on I-8 near Jacumba, doing about 80 mph with the cruise control on. I had to slow down for a car in front of me, so I hit the 'coast' button and slowed down to about 75 mph. Once the other car was out of my way, I pushed the 'accel' button to go back to 80 mph. As soon as I hit the 'accel' button, everything turned off, and I mean everything; engine, gauges, A/C, radio, etc. It was just as if I had removed they key from the ignition or something. So I put it in neutral, started it up again, put it back into drive and kept going. Everything was normal for the rest of the trip back to Arizona, but I did notice that the little red light on the dash (on my '03 it's in the center of the dash next to the clock...it's the light that flashes red when the factory alarm is on) was SOLID red. Once we got to Yuma to refuel, when I turned the car back on the light was off like normal.

I did a search and found some similar experiences due to the MAF sensor being dirty, but our car only has a K&N drop-in filter that hasn't been re-oiled, and this hasn't happened since. Just that once.

Any ideas on what this could be? I'm especially curious if the red light on the dash being solid had any importance? The SES light never came on, just that little red light on the dashboard. What happened, and what did that little red light mean??
