Yesterday I drove my Saab 9-3 downtown, when I returrned and tried to start it the car just cranked. Bought a code reader and found that I had no power to the ECM. Found the fuse blown. Replaced it and the car started and drove fine, until I had to shut the engine off at an intermediated stop. Blew two more fuses. Let the car get cold and replaced the fuse again. Started right up and drove fine. Question, Is my ECM going bad?

Thanks,
