Rob's suggestion of substitutions to eliminate the plugs, leads and coils is definitely the way to go, but only one thing at a time, or you won't know which bit was faulty.
I would be very suspicious of the TPS as Luddite suggests. I think a TPS fault could well produce the symptoms that you describe, but I would not try and substitute that from your good bike, rather try everything around it to isolate it as the culprit... You don't want to be messing up your good bike after all.

Thinking on.. It could also be a dirty or faulty injector(s)
