Could be the fuel pump or the pump relay or the filter, or an ignition problem.
Someone will have to determine if it is in fact fuel or spark related when it is running rough.

SOURCE: Car is running fine then

I had the same problem, but only when it rained. There was a crack in the ignition coil unit and the water was creating an arc. When I drove long enough to heat the engine and evaporate the water it would run fine. Strangely, though, I still had to stop and restart the engine. $150 bucks the replace the ignition coil, and now no problems (at least with that)

SOURCE: 98 gmc jimmy loses power to a stop

the fuel pump could actually be malfunctioning. and the reason that you are able to restart and drive again is because when you turn the key on it is allowing the fuel pump to pressureize your system. but while the fuel pump is continuasly running it is loosing the fuel pressure. this is common on the cheap fuel pumps. i am not sure about were you got the fuel pump from but in all of my experiances with this problem i find that the fuel pumps have been boughten at a napa store.
i hope this helps you out.
and you could attach a fuel pressure gauge on to the fuel rail and start the car and watch the pressure to see if it is droping.

If you suspect its a fuel problem best to do a fuel pressure test, you can rent a tester at auto zone and do it yourself. They also can show you how to use it and what pressure it should be. Also if you turn the key to on position you should hear a hum from the gas tank and then a click that is the pump running and the click is the relay, if you don't then the pump isent running, also chk. the fuse and relay, it could be as simple as a blowen fuse or a bad relay.

Possible faulty crank sensor or idle speed controller, fuel pump relay, or ignition module. Get a data scan and see what's sensor might out of range or defective. Check for clogged fuel filter also.

Shuts off while driving


The fuel pump gets power from the pump relay on startup, then from the oil pressure switch when the engine is running. You could try a jumper to the relay to bypass the pressure switch to confirm the problem. The design is to prevent a fire in a wreck.

The fuel pump will come on then, shut off when the key is placed in the ON position, this is normal. What is not normal, is when the key is turned to start the engine, and the fuel pump does not run when the engine is running at the same time. The initial power up you hear is a prime function that all vehicles have.

My 1994 oldsmobile 98 regency won't start


Check fuel pressure,spark.If no spark possible crank sensor or ignition module.If no fuel pressure tap the bottom of the fuel tank with a mallet while someone is cranking the vehicle if it starts then you will need a fuel pump.Also if you have spark and fuel but the engine feels like it bucking while turning over,take a hair dryer and heat the coils up.you may have a bad coil pack.After they get warmed it night then start as the coil resistance changes.
