Flir vue pro stops triggering after 5 triggers

I have flir vue pro r powered up using a power bank and usb cable. All the settings are as required.
But in multiple triggering mode after starting capturing the camera triggeres 5 times and stops triggering automatically.
I don’t know if it’s a power issue or something related to settings. Has anyone ever had this issue.

Thanks in advance
