Sounds like the little crimped stopped on the end of the cable came off. That happened to me once. Assuming all the other stuff didn't disappear, you might be able to crimp a butt-splice onto the end until you can order a new cable.
You should also see about setting the gas pedal stop properly. The little end crimp breaks off when it is set incorrectly. Push the pedal all the way down and then adjust both the pedal stop and the threaded adjuster on the TB so that the throttle is like 98% open. If the throttle is 100% open before the pedal is down, you will break the end crimp off when you floor it.
