At any moment, did the Check Engine light come ON? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. The possible causes for the problem you describe are many. My experience makes me suspect the Throttle Position Sensor (TPS), especially if there are no DTC's. The TPSensor (sofisticated rheostat) is a duo-circuit potentiometer wiich has developed (or is developing) bad spots resulting in erratic voltage signals being sent to the ECM. These voltage signals are used by the ECM to calculate 'LOAD' and is also used by the TCM (Trasmission Control Module) to know when to upshift/downshift.
These bad spots can be verified/detected using an Analog Ohm Meter

check for any circuit brakers near the fuse box, if theres any of them reset them by introducing a paperclip in the small hole and press, you will hear a click.

I just had this problem on a 2001 elantra. I took it in for repair: the MAP (Manifold Absolute Pressure/ intake air temp) sensor was shot. $150 later it works just fine.
