OBD II interface causes engine to cut out during idle and lights "check engine soon"

I just got a ELM 327 OBD II bluetooth interface. I grabbed an app called Torque for my Android cellphone and loaded it. Works great and I get some data. But when my 2001 PSD is idling after a few minutes the engine cuts out and the "Check engine soon" light goes on.

If I turn off the ignition, unplug the device and start her up it works fine. The engine idles fine without the device plugged in. I tested it several times.

Also if I use a different application but the same OBD2 bluetooth device, the same symptoms occur - cuts out during idle after around 30 to 60 seconds with check engine light on.

I'm curious if anyone has seen their 99-03 PSD cut out while reading real-time data using an OBD interface? Is it specific to this device, or is this a common issue?
