Narrative:
During cruise; the FMC 'dumped' on us twice. The first time; the data came back after a few seconds. The second time; the FMC erased the entire flight plan. The flight plan along with the performance data had to be re-entered in the FMC. Vtk appeared on both the mfds and a message (FMC1...invalid) came across the CDU scratchpad. Once everything was re-entered the remainder of the flight was normal. A logbook write up was entered at our destination.
