Timeout async/await

Как вариант, воспользоваться https://www.npmjs.com/package/promise-timeout

var pt = require('promise-timeout');
var examplePromise = example();
var timeOut = 1000;
pt.timeout(examplePromise, timeOut)
  .then(function (exampleRes) {
    console.log('example() returns result', exampleRes);
  }).catch(function (err) {
    if (err instanceof pt.TimeoutError) {
      console.error('example() timeout', err);
    }
  });
