Replacement was motor only , seems so strange that it’s been running fine for over a month and then has started with the same issue the last one had. I can’t figure it out.

Weird...
If it was just a motor swap, than I would look at replacing the trap filter lid/seal and maybe re-sealing the pipe joints. If you have a suction-side air leak that builds pressure in the filter, it will eventually get to a level that restricts flow (creates back pressure), putting a strain on the motor.
You can confirm by turning pump on and purging filter valve, then wait a while and do it again. If there was a bunch of air that purges the second time, you will know you are building pressure from a suction-side leak. Another "tell" is if there is any visable back-flow through the skimmer when pumps shuts off (let it run for a while, then pop the skimmer lid and observe the flow while someone shuts the pump off). If the back-pressure builds high enough it can actually "fountain" through the skimmers and pop the skimmer covers once the motor shuts off.
