I am hoping to measure time to completion or set a countdown timer to limit time on a given question.

I don't think a timer will work the way you are wanting. MATLAB Grader only has a transactional connection to a MATLAB worker. MATLAB is only running from the time they click "Submit" to when a result/grade is returned. After that, the worker they were connected to is reset. The next time they click submit, they get a new, clean worker. There is no persistance of variables or settings.
Are you running your course on MATLAB Grader or are you using LMS integration?

I am using solely MATLAB Grader for quizzes at the moment.
We do not have LMS integration at this point. Would that allow for the LMS timing system to control the access?

Unfortunately no, it wouldn't change the behavior of MATLAB Grader problems, but an LMS might provide additional tools to control how students view material in a course.
How are the quizzes assigned? Are they administered in class? Do students all start and stop at the same time?
I am adjusting how I do the quizzes. In class and timed ensures some consistency but with 108 students it is not easy to make sure they all finish at the same time.
I am also looking into mastery grading but this tends to lead students to google answers rather than try to complete it themselves.
