9910-P10 UPS (Exide PowerWare 9125 1000VA) problems ?

Has anyone experienced a situation where it appears this model UPS has
just shut down the load with no warning (similar to what the old Best
manufactured 9910-080 & 9910-140 UPS units used to do) ?
We have a customer where it appears the 400 has died twice with no
apparent reason.
There are frequently (couple of times a day) messages in QHST/QSYSOPR
indicating brief power interruptions where the UPS is working OK, and when
we tested it by disconnecting UPS power source and running on batteries
several times it worked OK.  IBM has replaced the UPS once already, so I'm
suspecting maybe the power supply on the model 270 could be at fault.
