RAK5010 powered down unexpectedly

Issue:RAK5010 unexpected powered down

Setup:RAK5010

Details:I have a tracker that sends GPS data to the cloud once every 5mins. But after 10-20mins, the module powers down. Im not sure if its due to high current consumption and thus overheating. I would like my tracker to last for hours. Hope someone can help. I do have BLE on to check the serial log.
