Default Blower motor resistor

I just replaced the blower motor resistor because the #3 speed didn't work. After installing the new resistor everything was good. All four speeds worked as advertised. After about ten minutes on speed #3 the blower quit working. #1,#2 and #4 still work normally same as before I replaced the resistor. Has anyone else had this issue? BTW the vehicle in question is a 2000 GMC Sonoma. I bought this vehicle new and haven't had any major issues in the twenty years I've owned it but this is frustrating.
