Blower turns itself on and off & thermostat is off

Coleman DGATO56BDE - furnace blower motor comes on and runs for several minutes and then turns itself off and will repeat this at random intervals and will only stay off if furnace is switched off at the control box or breaker is turned off. Thermostat is not calling for heat ... is turned off, and fan switch is set to off. If fan switch on thermostat is turned on fan runs until switched off - then will do the random on off again ... sometimes it takes several hours until it turns itself on. Any idea what part I need?
