Narrative:

On idale departure from las, navigation engaged at idale intersection, then aircraft went direct oal. During climb out, controller issued request to expedite climb through 14000 ft. As we were climbing through 12000 ft at 4000 FPM, the controller informed us that our track looked like it was taking us direct to oal, then issued direct shead. We complied. When we looked at FMS, this departure had dropped out of the system. We then complied with vectors. No conflict with other. Next time, doublechk departures in FMS.
