I always carried a spare fuel filter with me on that moto, even though it was usually the filter I had most recently removed as part of regular maintenance on that moto.
The R-GS uses a traditional large barrel-shape filter, the KTM uses a teabag construction. I think Mattinghofen went a bit anal with filtering and produced a conservative but easily clogged design.
I'm not sure if KTM recirculates fuel or not, but if it doesn't, as you say, then that could explain pump overheating failures.
