happens when you slow down to a near stop. so coming to stop sign/light, turning into someplace, traffic on the highway slows way down in front of you, etc.

when i duplicated the issue with the shop foreman, we were slowly approaching a string of cars at the light when it died.
I have a 30i auto. The one time it happened to me it was a hot day and I am certain (99%) that I was in sports mode. I also had the transmission in manual (I remember as I had to move back and up to 'P' to start the car).

I was coming to a slow stop at lights.

It hasn't been very warm here in the the UK (London) but the one time it did happen it was 27C so from all the other posts it would indeed seem that ambient temp is a major factor in the issue.

So based on this, what effect does a warm/hot day have on an normally aspirated engine? Is the fuel mixture changed compared to a cold day?
