LTspice stalled out

I'm running an LTspice transient simulation on a circuit with about 30 components.

The circuit contains a 455kHz IF transformer with an audio-modulated signal that's passed on

to a diode detector and then post gain to drive a set of headphones.

The simulation stalls out after about 3ms.

When I take out the two 100 MHz opamps, ADA4805s, and replace them

with two 1 MHz opamps, AD795s, the sim runs to completion.

(But the slower opamps don't provide the desired THD.)

I've varied the SPICE parameters over a wide range but the simulation continues to stall out.

Can anyone provide an explanation or some suggestions?
