A Dyson Ball Animal 3 that keeps stopping while you clean has almost always triggered its thermal cut-out, which switches the motor off when it overheats to protect it, and the overheating is caused by restricted airflow. It stops mid-clean, may restart after a rest and does so again, and the usual causes are a full bin, a blocked hose or a filter that is dirty or wet. Unplug the vacuum and leave it for an hour to cool, since a hot motor will not restart.
The checks in more detail
In the meantime empty the bin, check that the bin is not above its maximum line, and inspect the hose and wand by detaching each and looking through it for a blockage. A blockage that restricts air is the commonest reason. Wash the filter as Dyson directs, with cold water only and no detergent, and let it dry completely for at least a day before you put it back, because a damp filter blocks air and can damage the motor. Check the cyclones for a layer of fine dust and wipe them with a dry cloth.
Look at the floor head, where hair wraps round the brush bar and stalls it; a stalled bar can also trip a stop. Clear the brush bar and make sure it turns freely. If the machine stops only when the floor head is on a thick rug, the brush bar is pulling hard, so switch the bar off for hard floors, and use it only as directed on carpets. Check the plug, the socket and the cable too.
A damaged cable or a loose plug cuts the power and looks like a cut-out. Try another socket, and look along the cable for a break. A vacuum that stops after a minute even with a clear path and a dry filter may have a blocked part inside the machine's body or a failing motor, and for that you should contact Dyson with the serial number. Do not use the vacuum while it is protecting itself, and avoid vacuuming fine dust like plaster or ash, which clogs the filter and cyclones quickly.
