Not quite sure what your concern is with the top fill pattern. It is a load-bearing part, so it kind of needs to be the way it is to retain the part coming out the other side. As far as the extruder exiting the perimeter of the model, I would remind you of the possibility of printing more than one model on a build plate. Although, I hadn't yet considered trying to print only one to see if it still happens, as a troubleshooting approach. I'll try that later, to rule out the possibility that it's being mechanically pulled off by an extruder transport move.
Unless you've deliberately reversed your walls/infill printing order, the default is to print walls first. Your print head and nozzle won't have any reason to leave the perimeter of the model even if you're printing multiple examples of the part until the entire layer is complete on one of them. It will move to the next part in the array only after finishing the infill, which is well after your problem may have occurred on either the inner or outer perimeters on any particular layer.
I'm not sure what you're on about with top fill. I didn't say anything about your fill pattern or percentage.
