Pump issues

I have a 08 Viking Aurora spa. All worked fine but It started leaking from the seal on the impeller unit. I could not find a replacement so I had to buy a motor/ impeller assembly that was almost an exact match. It was an easy change as it was the same size as the old one. After install and refill I turned on the spa and it ran fine and heated up fine. After about 3 days the pump would not start. The pump would hum for about 10 seconds and then a click and would turn off. Tried resetting many time and would continue to hum and not start. 
so I drained and took out the new pump. I then took the old pump that worked( but leaked) and changed the impeller unit. So now I have the old pump on the new impeller unit. Hooked back up and refilled. Worked for 2 days and then hummed and wouldn't start. So question is what could possible make 2 pumps quit working. I only changed due to the leak of a seal and now have big issues.

Usually a blown start capacitor. Is the new pump the same voltage as the old?

The new pump pulls almost 25% more amps than the old. This likely translates to a 1/2hp difference in the pump. This should not be a problem for the new pump assembly, but could be a problem for the old motor with the new impeller. 

@CanadianSpaTech, any thoughts?
