Intermittent power loss

[knolldwight48@gmail.com]

I have a 2022 RAD Mini Step Thru with 1700 mi on it. Loved it at first until it quit on me. First time it blew the 40amp fuse on the battery. Replaced the fuse and it started again. Rode it for about 25 mi. and it blew another fuse. Replaced the fuse and it went twenty to thirty miles before it quit again. This time it did not blow a fuse. Just quit, no throttle, no assist, no voltage. Took it to a local, RAD approved shop. Shop owner took it for a ride as it magically began working again. Shop owner couldn't duplicate failure so he diagnosed it to be a bad motor. Thats a $450 part so I took it home. Rode it for about another 30mi before it quit again. Called RAD tech support and they diagnosed it as a bad controller which seemed logical to me. Bought a new controller, installed it, and rode it for less that 5mi before it failed again. Just stops. Anybody else have this issue. It's running right now but I don't trust it.

do you use full speed all often?  or nearly?  if so then you may have you battery wires over heating. 
I had to replace the battery cradle connector and the connector on the battery.  you will probably know this if it is difficult to remove the battery.
