APPROXIMATELY 5 HRS INTO FLT, THE RIGHT FMC FAILED FOR ABOUT ONE MINUTE. FMC CAME BACK ON LINE PRIOR TO QRH PROCEDURE BEING ACCOMPLISHED AND WORKED NORMALLY FOR THE REST OF FLIGHT. GROUNDED - YES. PERFORMED OPS TEST IAW B737-800 AMM 34-61-00-710-801 AND SYS TEST IAW AMM 34-61-00-730-801. BOTH TEST PASS, NO FAULTS FOUND.
