Thanks for the link. It was a good article and I looked at some other articles on that site too.

I've been wondering if this is a symtom of the stalling problem. Perhaps when it stalls the computer loses its data and has to start the learning process over? Since you're on the line, I'd like to get your thoughts about the stalling problem.

I kept a log for a week to track the stalling incidents:
On 5/8 cold starts it stalled exactly two minutes after, then restarted fine.
the other 3/8 no problem.

When hot it would stall between 2 and 15 minutes after starting about 50% of the time.

On long road trips, it will drive 100-200 miles trouble free, then stall once or twice after stopping.

It always restarts, and restarts on its own if cruising over about 20 mph.

Thanks again, TX
