Has anyone here used the Sparkfun Photon Weather Shield with external power (e.g. not powering through the photon's UBS port)?

I have the shield set up with a complete set of sensors, and a sketch loaded on the photon to read them. It all works fine when powering the photon via the USB port on the photon board itself, but when attempting to power the device from the barrel or screw connectors on the shield, the photon continually resets just as it enters the setup routine.

Has anyone seen this behavior with the Photon Weather Shield?

Thanks!
