   1. Clean off any corrosion or debris
   2. Check for imperfections in prongs on the power board as well as battery.
2. Check all the cables coming out of the power board.
3. Check your error history for any possible esc errors.

3. Replace the faulty esc if that is found to be the issue. 
4. Mark battery and if it happens only with a specific battery replace it.
5.  If it happens with all batteries, replace the power board.
