2009 Chevy Silverado 2500HD WT.

Blower motor has a mind of it own. It works fine on all speeds and then shuts off. After a few minutes it will come back on.

 

The motor is probably getting hot causing the relay to break the connection, recommend checking the wiring to include the ground wire to the motor and if they are fine remove the motor to see if there is anything rubbing on the cage causing friction.
