My s/s hasn't been working for the last 6+ months. Tonight it worked. I noted that the outside temp was 78, whereas the temp here in SE FL is usually 80+ to 90. Could s/s be temp related?

Yes. It considers the A/C load related to temperature, and will not shut the engine off if the evap temperature isn't cool enough to compensate for the outside temp versus desired a/c setting temps. So if it's hotter outside, it shuts down less often and for shorter times. Perfectly normal.

Eco stop/start looks at a ton of parameters before deciding to shut down the engine. I think the full list is about 80 things.

Thanks, Joe. I made an appt with MB last week over this issue. Car is to go in this Friday; however, as the temps are cooling below 90, I'll first see if the s/s works during the next two days before changing the appt.
