You are running out of power. I'll bet your regulator on the Arduino is getting a bit warm.

edit: If you are using the USB power, the resettable fuse is just about to shut down the power.

I do feel a little bit of warmth in there - I take it a proper supply such as mains would help that along?

I'm not sure that would help, but you can try. The Arduino has a linear regulator, so the closer you can get the Vin voltage to 7 volts, the better. Otherwise, that much current will cause it to get hot and fail.

There are discussions on the forum on whether it is ok to power the Arduino directly to the +5v rather than Vin. Some boards have been damaged by the attempt. The last I heard, The Arduino crew recommended you not do that.
