The ISS actually went over half an hour after, at 22:20 central time, passing through the exact spot you mentioned.
Around the time you specified, though, there were several satellites in the vicinity: SL-3 R/B @22:09, NOAA 17 @21:58, Intercosmos 25 @21:47.
The duration (15 seconds) would lead me to believe it wasn't a meteor, as a meteor entering into the line-of-sight would have appeared, gotten
brighter over maybe a second, and then disappeared. It would never have lasted 15 seconds.
Also, over the course of 15 seconds, you should have easily noticed any motion if it were a satellite, and, when satellites disappear, they typically
do so over a period of several seconds. And, especially in this case, for the satellite to not appear to move over 15 seconds, it would have to be
moving extremely slow...which would cause it to disappear at an even slower rate. As far as I know, a satellite would never disappear instantaneously
(even in the case of an Iridium glint).
It's also possible for objects, like asteroids, to occult stars, if they happen to pass directly between the observer and the star, and happen to be
large enough and/or close enough to block the star's light. However, this would be short-lived, and the star would certainly have reappeared within
the 5 minutes you continued to watch.
To sum that up, I guess, I'm not sure what you saw. And, the fact is, many people have had similar sightings. It's not a rare phenomenon.
ETA: as I've said, the other thing it was not is the death of a star. Stars "die" much slower, and the reduction in luminosity occurs over a period of
days, even weeks. Star death is not instantaneous.
