Hi Amy,
I cant think of anything off the top of my head that would cause it to slow down, as long as there are idle agents and enough valid interactions to be presented. Have any configuration changes been made to the campaign or the agent utilization etc? If nothing has been changed and you have examples it maybe worth of a case with customer care.
Dialer is not my strong point, so someone else may have a better idea of what could cause this
