blower a/c was going in and out, then stopped

The blower on my a/c was going in and out, then stopped. I took it in, they said needs new radiator so they put a new one in, did a coolant flush,

Then when I left the 2nd time going somewhere tonight my engine light came on, the car's power seemed to be affected, then when I was almost home it died on me at a stop sign. After about 7 trys it starts again and I made it in my parking spot. what happened?
