Fuel stop solenoid, '86, 22R, 4Gear

Toyota pickup 1986, 141000Miles, 22R, 4cylinder. I recently had the carburater rebuilt, new spark plugs, spark plug lines, rotor and rotor cap. It ran very good for two days and then it would turn off while I was driving. Everytime I don't give it gas the motor will turn off. Toyota diagnosed it ans it said it was a "fuel stop solonoid", my question is if there is another name for this part, because I can not find it, the closest I have gotten to is a "injection pump solenoid" or maybe an "idle stop solenoid."
Thanks.
