Hardinge Fanuc 21i-TB x axis error codes. Help please.

Having issues with a Hardinge Conquest GT27-SP gang tool lathe ( bought new 2006 ) running Fanuc 21i-TB.

This morning had the 300 APC alarm. Changed batteries. Reset X axis
Zero position.

Reset tools. Then the job ran fine for about 20 minutes after axis reset, then just stopped running during cutoff.

(The job had been running for 2 weeks with same feeds and speeds, stock, etc,
so no changed parameters. Machine runs about 6 hours a day).

Codes displayed after it shut off :

453 X AXIS:SPC SOFT DISCONNECT ALARM
300 APC ALARM : X AXIS NEED ZRN
362 X AXIS: ABONORMAL REV. DATA(INT)
367 X AXIS:CONT MISS(INT)

To be clear. I had the 300 alarm, changed batteries, reset X axis zero position,
job ran for 20 mins then shut down during cutoff with the codes above. Battery was new.

Have read maybe bad cable. Oil intrusion, etc.
I’ve taken all of the covers and guards off.
All connections look clean and dry.

Any ideas on what the issue is given the list of codes?
Any trouble shooting steps I should take?

Any help much appreciated!!
