No motion for new trial or motion in arrest of judgment shall remain pending in the trial court for more than sixty (60) days after the pronouncement of sentence, except as provided in this section. A failure by the trial court to rule on such a motion within the sixty (60) days allowed by this section shall constitute a denial of the motion as of the sixtieth day; provided, however, that with the express consent of the prosecutor and the defendant or the defendant’s attorney, which consent shall appear in the record, the motion may be carried past the sixtieth day to a date certain; if not ruled upon by the trial court as of the date to which the motion is continued, the motion is deemed denied as of that date, unless it has been continued again as provided in this section. The motion may be continued from time to time as provided in this section.
