Yep sounds like limp mode to me. My manual Z did it when I first got it and was still getting a feel for the transmission. I stalled it out at a red light and then real quickly tried to start it right back up. It started but was in limp mode until I parked it and let it sit for about 10 minutes.

Update 2020:

I expect to be made fun of, but I had it happen again, and this time an SES light came with it. Turns out I didn’t tighten my gas cap enough ��. Just in case anyone else has this issue.

Really? Not being a smart@$$, but the gas cap doesn't take much before it's tightened. My gas cap barely turns 25 degrees before getting the tight click.

My car sometimes does this where it feels really sluggish (due to dirty MAF sensors per the obd II scanner). You don't have to wait 10 minutes, but rather, turn the car off, open the driver-side door, and the start back up.

That or just clear the codes with the scanner.

Yeah, I always feel like it doesn’t take much to get the first click, but when I had the codes checked it was throwing 12 repeating codes for the fuel door not being turned enough. Maybe with my Z approaching 200k, the sensor there is just “old”. So I just make sure it’s for sure snug now.

The sensor is a pressure sensor. It doesn't care if the cap is actually there as long as the tank is sealed. It's possible that the sensor is going bad but that would be very low on my list.

Check the threads where the cap screws in and make sure there is no dirt. Check the o-ring on the cap (a very small coat of grease may help it seal*).

It might be time for a new cap.

*The grease will tend to capture dirt but only when you have the cap off.
