Motors stopping at different times is normal. The main factor is the resistance from the drivetrain usually caused by different belt tensions. It’s very difficult to get the tensions exactly the same, but it is healthy that they are similar. The perfect tension is 5-10mm of play on each side when pinching the belt. If it is too loose or too tight, this may cause concerns.

Another factor could be the bearings. Ensure both motors are spinning freely by rotating them manually.
