This is an electrical malfunction and is what is referred to as a "global" malfunction. That means a principal circuit, or circuits, was interrupted obviously on an intermittent basis. Battery terminal corrosion is possibly implicated at least as a contributing factor. What you can do to minimize the chance of a recurrence is request an electrical inspection and the mechanic will address and resolve visible, and testable, faults or deficiencies in the main cabling, the power distribution box, fuse holders, and so forth. In addition, the battery should be load tested, and charging system output should be confirmed to be sure that those components are not implicated. If you request the electrical inspection, the responding certified mechanic will perform those services and further advise you at the completion of his/her work, right at your location.
