Since the pine64 is powering off... it sounds like it isn't seeing a valid boot device. er, scratch that... I just double checked, and it didn't do what I thought... , as I thought the pine64 powered off after 30 or so seconds if you powered it on without a microSD card present...
It's going to be hard to debug what's going on, because at the moment, it is a literal black box. Do you have a USB to Serial adapter / cable which you can connect the the GND and Tx pins on the EXP header (have a look at the pinout guide in my signature, and connect Tx on the pine64 to Rx on the USB to serial adapter). It doesn't need to be a 3.3v tolerant as you don't need to connect to the Rx pin on the pine64, and regardless of that, the EXP header on the pine64 appears to have a mosfet level shifter on the serial Rx line (but all the other pins are 3.3v IOs only). If you can give us the output you get when powering up the board when it doesn't want to work properly, we might be able to work out what's going on. Other than that, what dkryder sounded plausible... except that wouldn't happen with a squeaky clean new (old) image which hasn't even been let online yet.
