i would start with refreshing the firmware, then re doing motor detection while also checking all of your wiring, then make sure that where your are located there isn't crazy amounts of rf, it can interfere but very unlikely, there is a study done buy 2 guys who hacked and controlled a boosted board e-go ad evolve just but filling the 2.4 spectrum with noise they did this because the same thing happen to one of them on his boosted board.
I just downgraded to 2.7 and re-configuring it, but probably wont ride in the next few days, i live in a few kilometers away from town, and i was ridding in the road that connect it to the city, so not much there except from a low voltage power line that was more than 10m away, and i rode this exactly place lots of times
But in this case you mentioned they did that by confusing the raio input, since in my case i were full brake for the motor, a lot more than i can get giving full brake in the remote via current control i suspect something happened in VESC itsel. I re-checked all configuration and there was nothing that would cause full brake in case of signal loss

hey pedro, sorry for that... which transmitter were you using?
I am using the NRF modules with arduino and connected to vesc via PPM, as i said above, due the nature of the brake force i don't think is was related to radio communication, in the arduino code i have a fail safe to reset everything to neutral in case i get radio drop or problems with communication
Did you update to 2.8 yet?
EDIT:
Hum, apparently my NRF module was a little loose on the connector, i was delaying to weld everything because i was ridding a lot lately , but even if it came loose it does not explain the full brake
EDIT2:
And again, apparently my fail safe is not so safe in fails, it works good with a signal loss, or if the remote shut down, but if remove the module the PPM output goes crazy and start to oscillate between 0 and 100% at random several times per second
Maybe this could cause some trouble on VESC? even after i could get up again the motor remained full on full brake
And a tip for everyone duct tape is not a good measure to prevent vibrations from disconnecting connectors :|
