Per Sheila's suggestion, went to ADJUST_POWER after COIL_DRIVERS. Set to 25 W and then went to ENGAGE_ISS_2ND_LOOP. Lost lock again in ENGAGE_ISS_2ND_LOOP.

Tried skipping from COIL_DRIVERS to LOWNOISE_ESD_ETMY. After a while in LOWNOISE_ESD_ETMY, it seemed to be stuck, so I requested NOMINAL_LOW_NOISE. It still didn't move on, so I re-requested LOWNOISE_ESD_ETMY. This broke the lock.
