Dying while driving

Was driving my sisters Ford edge when it died in
an intersection. Got it started long enough to back
it up out of the intersection before it died. Dad took
over driving and got it about a block before it died
again but this time while the vehicle was moving
and now it will not start at all. When the vehicle
died while moving the low oil light came on
(because of the fact that the engine was not
running but vehicle was still moving) and oil levels
are good upon checking. What could be some
possibilities of what is wrong?
