Oil light flickering and engine cut out

Hi was driving work the other morning, car pulled out on me I touched my brake and the oil light flickered on and off. Carried on another 200 yards or so and turned a corner and the engine died on me. Dash lit up, all lights on. Tried to start the car was turning over but wouldn't fire. Had it recovered to my home address, a few hours later, my dad went to check it over and car started straight away. Oil level is fine also. Daren't drive the car as with loss of power, power steering becomes heavy etc, any ideas people?
Ps the dash light of the little car with a spanner symbol has been popping up intermittently over the past couple of weeks, related?
Thanks emma
