Regardless of setting, auto, low, high, the windshield wipers will work fine for several minutes, then suddenly stop in the middle of wiping stroke. Turning the switch to off and then back to any setting 2 or 3 times allows it to start working again for a few minutes until it stops working again.

I;m suspicious that your switch is failing, and second to that, I'm suspicious of the motor or park switch in the motor. Get to the electrical connectors at the motor and check with your meter or testlight and see whether or not the motor has power when it fails. Or take it to an auto electric shop or Lexus or Toyota specialist.
