The error in the attached picture(FCFF1043) is for 16 I/O card located in CIO slot one for board transfer. May be thats when your PDP supply drop voltage. If problem comes back, look at that card and/or connection and/or cable.

Check Power Distribution Panel Power Supply. No output or output too low for 24V, 15V, and 12V. Also, LED's on PDP LT6, LT7, LT8 , LT9, LT10, LT11 don't turn on at all, even though all fuses test OK for continuity.
