My ceiling fan will run for 30 seconds to 1 minute when I press the fan speed button on the remote but then shuts off on its own. I switched the batteries in the remote with others from another remote but it still does it. Question is: Is it the remote or the fan itself.. like a module or something?

Module.. . Trying switching the frequency of the fan and remote using the dip switches. See:
