A Shark Navigator Lift-Away that keeps stopping in the middle of cleaning is very probably protecting its motor, and the cure is to find what is making the motor overheat. This is the NV360-series corded upright, with a detachable canister pod, washable filters and a HEPA filter. The vacuum has a thermal cut-out: when the motor gets too hot, because the air is not flowing, a switch cuts the power. After a rest of about half an hour, the motor cools and the vacuum works again, and then stops again when the blockage heats it.
The checks in more detail
That cycle is the pattern of a machine that keeps stopping. Check the airflow, which is almost always the reason. Empty the dust cup, which should not be filled past its line. Remove and wash the foam and felt filters, which clog with fine dust and must dry fully for at least 24 hours before refitting, and check the HEPA filter for dust and clean or replace it as the manual says.
Look into the hose, the wand and the floor head for a blockage, which you can find by looking through each or by passing a long, soft item; hair, a sock or a toy is a common cause. Remove the brushroll and cut off wrapped hair. A pod that has not clicked fully back onto the body can also leave the airway open and the suction poor. Then the power.
Check the cord and the plug for damage, test the socket with another device, and make sure the cord is not caught or stretched. A loose connection at the pod's contacts can make the vacuum cut out when it flexes, so reseat the pod firmly. Let the vacuum cool before testing. If it still stops with clean filters, a clear airway, a seated pod and a good socket, the motor or its switch may be failing, and SharkNinja can help with the model series NV360 from the label.
