why my jetson nano always shutdown?

1,When i run ./imagenet-console.py --network=googlenet images/orange_0.jpg output_0.jpg,Turns off after a few seconds。
2,Sometimes the browser will shut down after opening it for a long time.
power is MAXN==10W?
supply power is 40pin->5V 5V to my big power LI-po battery and usb port 5v 1A

Hi, can you try 5V 4A power supply on DC jack to see if it is a power supply issue?
