PiRLP Suddenly Not Working

Russ Woodman
 

Hope someone can help me with this. Have an IRLP board pre-modded to run on 3.3v coming off a Raspberry Pi 2 (wired only). Finally got it hooked up and working earlier but after firing it up a second time, Pi will not boot with the PiRLP board connected. Disconnect ribbon cable, Pi boots fine. Re-connect, nothing. Disconnected 3.3v jumper on PiRLP board and Pi boots fine, presumably because it is not getting power. Ribbon cables are connected correctly and this was working (one time) before bringing it home to power on again. Any help would be appreciated.
