Stalling while running normally is definitely the fuel pump relay or fuel pumps. Replace the relay and check the current draw on the pumps -- replace pump if it draws too much, else it will just fry another relay (there are two fuel pumps -- a dead one will cause serious running problems as the other one will not deliver fuel correctly with a dead pump in the line).

ABS light coming on is the OVP, replace it.
