The positron resides inside the neutron. There is no reason for the

The positron will be subject to EM forces that the neutron is not.
The neutron will be subject to residual strong forces that the positron
is not.
If there is no force keeping them together, they will over time drift apart.
It's not like the neutron has "walls" that can keep the positron in.
Quarks stay inside a nucleon not because there are "walls" but because
of the strong force (which gets stronger as the quarks move further away
from each other).
