Question about 1998 Hyundai Elantra
It seems like a simple tune-up is all that is needed.
Change the spark plugs, the air filter and clean the throttle body.

The engine in your car is controlled by a computer, it is called the PCM (powertrain control module), the electronic system (referred to as the OBD2 engine control system) is very sophisticated and takes special tools to diagnose problems like this, in the case of this particular problem it can be caused by any number of failing components in the engines electronic fuel injection system, when these problems occur the computer (PCM) will detect the fault (the loss of power you felt) and it will record a fault code (there are over 200 codes) in its memory, these codes can be read with a special OBD2 system scanner or a OBD2 fault code reader, you can also go to any Kragen auto parts store or Autozone and they can read the codes for you free of charge, but I highly caution you on accepting any advice from them as to what the problem is, they are not trained electronic engine control technicians, that takes years of special schools It is my opinion that the best thing to do is see the local Hyundai dealer to have the electronics diagnosed by trained Hyundai technicians.

First off is the check engine light turning on at all? Did you buy the car through a dealership or through private sale? How many miles are on the vehicle. Was it during idle that it was dying or was it under load(while accelerating) that it happened? Once I have more information I can assist you further. If a check engine light is on you will want to take it to the nearest autozone and they can tell you what the trouble code is in the vehicle and that will narrow it down significantly.

If the car has never been tuned up, replace the spark plugs, spark plug wires, distributor cap and rotor, air filter, and fuel filter. More then likely your fuel filter is very dirty causing the gas flow to become interrupted. After you change all this and the vehicle continues to die out then you will need to check your fuel pump with a multimeter for continuity. A bad fuel pump would cause the vehicle to die. If the fuel pump is good then replace your oxygen sensor.

There are numerous possible causes for this behaviour. It could be as simple as a faulty spark plug or it can be a fuelling issue or problem with emission sensors on the vehicle or a problem with the ignition coils or even the fuel pump.
When was the vehicle last serviced and has it had the spark plugs changed? This would be one of the first items to look at as would replacing the fuel and air filters.
The symptoms you describe are also in keeping with an EGR fault but a diagnostic scan is needed to confirm this and avoid throwing money at replacing components unecessarily.
If you bought the vehicle from a dealer I suggest you get on to them pronto to have the fault rectified. If it was a private sale then there is no come back in that sense but you should contact the seller to check what work has been done recently. If the plugs have not been changed in the last 40,000 miles they need to be replaced and the fault may well resolve following this.
The next suggestion I have is to get the car to Autozone and have it scanned for fault codes. Autozone will do this free of charge and any stored error code will point you in the right direction as to what component is causing the problem with the EGR valve as an example.
Hope this helps get you pointed in the right direction. Thanks for using FixYa.
