it's not possible to help without more information on "simulation stops". is
there an error message, either in the sander output or output from any
queueing software? does the simulation stop, or keep running but not produce
output? does a non-REMD (normal MD) simulation work fine for the dimer using
exactly the same input but not exchanging?
