Radiator Fan issue

[napajs13]

With my car off (not runningg) my radiator fan was not spinning when I turn the a/c on high, so i tapped it with my finger then it started spinning slowly. So i replaced it and turned the ac to high and the replacement was spinning at what looked and felt like normal operating speed. Then I started the car and it was running for a bit, until a few seconds later, it stopped like the previous fan. Would the temp sensor in the radiator cause this problem? Any suggestions? Any info would be great. Thanks!
