The TPS is located in the TB/ECU combo in EUro5 bikes. It is inaccessible to piggyback ECUs which is one of the major flaws of the E5 version (all bikes, not just the Hima).
In the E4 versions there where various options to deal with stalling all of those are no longer available thanx to idiotic emission laws.
What I heard (not tried myself) helps is adding the FuelX Pro which of course is not free. Or the PT4, even more expensive and you have to know how to do mapping.
Depending on location, fuel quality and the km run (tell us more about your bike) it could also be a dirty fuel filter, a weak fuel pump motor or dirt in the TB to name a few reasons. Error like these suck.
