Mass Air Flow Sensor problems of the 2000 Cadillac Eldorado

While traveling at 65 mph the engine quit in the middle of the I-35w bridge over the mississippi river in minneapolis. I managed to coast safely to a stop on an exit ramp about 200 ft from bobby and steve’s auto world. They spent four hours trying to figure out the problem was. They found the ecs fuse had blown but they were not able to determine what caused its failure even after four hours of working on the car. They replaced the fuse and everything began working properly. The problem had not reoccurred as of this date. I bought a package of five10 amp replacement fuses and put them in the glove compartment. I was told that ecs fuse supplies the power train control module, the agr valve, the evaporator canister purge valve, the ignition one relay, the mass airflow sensor, and the trans axle.
