Could be low or restricted fuel pressure or flow, a fuel pressure test should tell you that, may also be a bad TPS, a live data scan will need to be preformed to confirm that. After the engine dies the power steering also quits as it is powered by the engine, and the brakes need vacuum to make to power booster work so no vacuum cause the engine is dead so no booster for the brakes.

Check the sparking system. It may just have a bad rotor and distributor cap. Every once and a while the coil will go and some times the control unit will start to go. I would say Do a general maintenance on it plugs rotor distributor cap and cables if you open the dog house and see a light show like these mini vans often did.. especialy in damp weather
