I don't think stopping and restarting will help anything (except breaking
up a run can save problems from restarting from scratch after a crash).

I believe you are pretty much forced to use iwrap=1 and ptraj to image
everything, tho you can keep the solute from moving 'far' by removing
net momentum periodically.
