How can I fix my Dyson DC05 ?

Have it about 5 years....used once per week for 30min each time. Lately it cuts out after about 15min and restarts by itself about a half hour later. Seems to be some kind of thermostat problem.
Can you advise, please, as to likely cause ?
Thank you.

"Freely" in this context means several sources - not zero cost.

They have a thermal cutout / fuse / safety device - to prevent the motor getting too hot and catching fire.

Freely available on line...
