I have a Hydropool hot tub that I've owned for about 10-15 years. It runs just fine until I run the pumps (there are two separate pump motors) at a higher speed and then switch them off from the hot tub control panel. It will then trip the GCFI breaker.

The breaker I've had installed for years was a 60 amp GFCI. Someone suggested I replace the breaker. As a result of upgrading our pool, we had to do some additional wiring and ended up replacing the breaker for the hot tub to a new 60amp GCFI. The issue with tripping the breaker continues.

I'm having trouble understanding why the hot tub will run continously with both pumps on high but will trip the breaker when turning the pumps off. Could this be an issue with the motor(s)?
 
My guess is you have a suction air leak that is spraying water when the pumps shut off and the water is hitting some electrical connections tripping the GFCI.
 
You were correct. The pump seal where the pump attaches to the motor was leaking, allowing water to spray into the motor.

Now to find out where to order a replacement pump.
