It may have just been a computer glitch. If it comes on again try checking the battery's state of charge. Sometimes a low voltage can throw up glitches from time to time on some models.

SOURCE: why is it shutting off and my rpm gauge is acting crazy

My problem was the same. It was diagnosed as needing a new Crank-shaft Sensor. Replaced it and it ran great. Very difficult to get to physically!

The code that tells why it died is the P0068 the throttle position sender. It can be bad but they usally last a long time. Other sensers can have troble and pull down the 5 volt reference signal and it'll make it appear that the senser is bad. You can pump the gas very quickly many times and make even a good car set this code. The computer sees a smooth signal from the senser it'll set things back to normal and it'll run just fine. The senser can be teated with an OHM meter center pin of the serser to one or the other outside termial. with the meter making a good conection. the senser should make a smottth change up and down and return to the same value as you started and never go off scale, the other terminal should do the same thing but only in the opasit direction. If it doesn't its bad but a new one stick in on fire it up and run down to the store and have them erease codes telling them you replaced the bad part and need to reset. Even then they sometimes won't do it as some stores have run into troblem with the wrong customer and they don't reset codes anymore. Then you'll have to go to a shop the has a code reader or a scanner to reset the light and or buy your own but about $80 is the cheapest you'll see for a reader that will reset (erease cdes) on OBDII vehicals. good luck

SOURCE: Car won't start after filling up the gas tank.

Just helped a friend fix this exact same issue on his 2004 hyundai santa fe. Replaced the purge control valve - a $39 part, even from the dealer. Had to get our hands dirty, but it took literally one single hour to replace the part. Filled it up immediately afterward and no more starting problems. Part is located directly behind the manifold - top, rear of the engine compartment - just between the engine

My engine light keeps coming on and my gas gauge

The check engine light means you should have the engine computer checked for trouble codes. The gauge problem could be the sending unit in the tank.

Front axles

you have speed sensors and tone wheels on all the axles so I'm thinking that you have some cracked tone wheels on the axles that set codes in the PCM

Start problem after filling gas tank

is the check engine light on, and have you checked the computer for trouble codes ?
Sounds like the idle air control valve is sticking but that would not have any effect with the gas tank.

Code P0501 vehicle speed sensor A range/

I found an answer to this in the reverse direction. While changing my front brakes, I noticed that the sprocket pickup for the speed sensor on the front passenger side half shaft that works with the sensor was cracked and ready to fall off. I removed it so that it wouldn't fly off and puncture a tire. I do NOT have Anti Lock Brakes on my 2001 Santa Fe. I started up the car wondering what to expect and experienced a P0501, P1529, P0500 and a second P0501. Looks like it time for a new half shaft (Axle).

Will start but rpm gauge jumps up and down then it dies

The problem you describe has NUMEROUS causes. Most common of these is a COIL is going bad. The RPM gauge gets its signal from the ignition coil/crank sensor circuit (could be either one OR could be the wiring between the engine control module (ECM) and the engine components. Does the Check Engine light come ON when this happens? 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. Once you do this and let us know what, if any codes are set, then we can go from there.
