why did the oil pump fail at 11700 and with no warning,the fluids where fine on 1997 Oldsmobile Cutlass Supreme

it stalled then ran fine for 10 miles i heard a pop and the oil light came on, the car shut off,my mechanic said the oil pump went and the fluids were good,he doesnt no what caused it,but has to replace the motor,only running on 5 cylinders..did someone tamper with my car?
