Hi,
Do you know why the attached LTspice sim just stops working at about 56ms?

Why all those -5V supplies rather than just one? Why 2 x 10uH inductors in series at the output rather than one 20uH inductor? Unnecessary components and circuit nodes will slow down the simulation.
Reducing the number of RC filter stages at the input gets the sim to run past the 56mS point.
Like Lightium, I found missing pin connections. Perhaps the IC model asy files you use are not the same ones as I use. Analog Devices may have updated them?
 
Thanks, i fixed it up now, but its extremely slow, .any tips on speeding this particular sim up appreciated?
