The owner of the machine said that even with the thump, it played more than three sides. However, the thump was so bad at one point that the needle jumped. I winder if it was so bound up that one or more of the springs acted as if they were smaller/under more tension and so powered the motor longer but not the full 20 min. I also suspected that the springs may have 'softened' over time but I will try George Vollema's gear suggestion before I do anything else.

If so how long did it play? A good four spring motor should run about 20 minutes. If it didn't, it's possible that the springs have lost some temper and are weak. The only other possibility is a bad record or needle but I'm sure you thought of that.
