Pixracer with px4 airspeed sensor (MS4525DO), i2c splitter. On battery power.

For some reason I can only get airspeed to work when nothing else is plugged into the splitter. If I plug in a gps I will get satellites but airspeed will stop reading. Has anyone else had this issue?

MS4525DO is a quite picky for i2c voltage levels, cable length and termination. The best solution is to use an active i2c hub, which takes care of the necessary signal conditioning.
