You have made the common mistake of choosing a motor with an excessively high Kv. Unloaded that motor would spin over 50,000 rpm, but loaded it will draw too many amps, overdraw your low-power battery and shut down the ESC. The only solution is to choose a more suitable motor with a Kv under 2000. Switching to a 2S pack may work, but you will probably see the same issue.
