## Discrepancy

APU BLEED JUST SHUT ITSELF OFF AFTER SEVERAL MINUTES OF NORMAL OPERATION.  DUE TO RECENT APU BLEED HISTORY, ACCOMPLISH SERVICE TIP. IF NO FAULTS FOUND REPLACE K10645 (562-0439).  CONSULT ON-LINE IPC TO VERIFY PARTS LIST CURRENCY.  ACP'D SERVICE TIP 36-11-00 P500A AND NO FAULT NOTED AFTER 30 MINUTES APU RUNNING.  REPLACED K10645 ON P36.  RAN PACKS AND MOTORED ENGINE WITH APU BLEED SHUTOFF VALVE OPERATING OKAY.
