Intermittent power
 

Hi all, I'm running my Anderson m5 cross with the skyrc leopard 4370Kv brushless motor and 60A esc with 3300mah 2s lipo's, which has been running fine until today! All of a sudden, it's starting to run intermittently it will run well for 30 seconds and then the power goes, I ease off the throttle and it then jumps back to life for a while and then the same thing happens again! Any ideas please as I'm new to this hobby

thanks

ZLiPo's not charged or a high impedance or intermittent connection somewhere between the battery and the ESC.
