The battery is okay I assume because it actually turned over and started, but it just wouldn't stay running initially. Could this be the result of not starting it in over a week? Any thoughts? Thanks

I just had this happen, but slightly different conditions.
I bought my father's 2002 (Build 11/2001) 3.0 X5 about 3 weeks ago - he got a new E70. The car has about 180K miles on it and has been regularly serviced.
My wife drove it to work this morning, and at the end of the day called me to report it would not start. When I got there I turned the key on and the battery seemed strong. It would start, rev up as it normally does, and within 3 seconds or so shut off. I started it several times with the same result, but then found I could keep the engine running if I put a little pressure on the accelerator. I stabilized it at around 1,000 RPM, put it in gear & drove it around the parking lot. As long as I kept power on the engine would keep running, but taking my foot off would lead to the engine shutting off.
By the time I got there the SES light was illuminated continuously, and I was prepared to flatbed it to the (now-closed) dealer. However, I was loathe to park it overnight on the street where the dealer is, and it seemed to run fine, so I decided to drive it home. It did shut down once when I accidentally took my foot off the accelerator coming to a stop light a couple blocks from where I started, but then I got on the freeway and drove the 12 miles back to the house with a minimum of excitement, being careful to keep power on and use the brakes when I felt I needed additional load. Freeway speeds were up to 75 MPH, and the fuel consuption (rough guess from looking at the needle) and performance were right where they always had been.
I got home and parked the car, and shut it off. On a whim I restarted it - and it idled just as it always has. The SES light, of course, was still illuminated, which I expected. So I walked the dog, did a few other things, and when my wife got home about a half hour later I fired the X5 up again and drove around the neighborhood, and all seemed normal. I then noticed that the SES light was no longer illuminated - which I did NOT expect. I drove a few miles, filled it up with gas, and drove home - working perfectly.
Searching this site, this is the only thread I found which describes a similar problem, and other boards haven't given me much, either. This car is driven every day, and the previous owner (my father) never had this happen to him.
Now that the SES light is off, will there still be a record of what the code(s) were that caused it to light up? Has anyone else had an event like this? I plan to let it cool off overnight to see if it's related to engine temperature (which it seems to be), but if it does start up in the morning I'd still like to know what was wrong.
Thanks in advance from a new X5 owner, but long-time BMW owner.
