Same issue here. About 80 miles in on my new RadRover 5 had cut-outs that lasted 15-30 seconds while riding but no error codes, the display showed 000 Watts for the duration.

Rad sent a replacement controller - and I concur, excellent customer service. About 120 miles in after replacing it happened again, this time it seems a bit more often and on shorter durations. Sure enough they shipped out yet another controller and a battery tray this time. Hopefully it'll be the end of cut-outs.
