First weird thing ever happened

I have a Infi I30 '96. It has 108K miles on it and it was alrite ( as long as i know, I am the second owner). But this shit happened to me this evening and I couldnt understand why.
I started the engine and it just shutted down by itself, it was like when you drive a car out of gas. I waited for a while then start it again, same thing happen. But the thing is when I hold the key for a while, it worked.
I thought it was okie so i cruised around and it messed up again. SO f&(*&ing wierd.. ANybody knows wat is going on with it ???

dont want to sound stupid or anything but this happend to my 1st car.... which was my learnign car when it didnt have the tuneup... tuneup and it was fine.... then sold it cause im shure i messed it up pretty nice trying to drive it messed up.

I took my car to the car shop and they couldnt findout wat was going on. Now it is running again. but it wasnt fuel or tune ups either. They told me to take my car to the Infi dealer .. shitt..... dunno wat to do ... no moneyyy...

ahh well im sorry friend but thats all youc an do... i mean take it to the dealer and they charge an arm and leg jsut to check whats wrong with it... so i dont know.. money is an issue..

3 more hours computer dianogtic.. whenn .. none... It seemed to be alrite.. everything ...
I told the shop to check the gas for me.. because I guess I got some bad gas... and probably .. in the tank .. half is gas and half is water ... That would explain why the car just stop all sudden for nothing. Anyway .. they told me it is waste of time to do it because the chance it happened is 1%. Ehhh .. I took my babie out with no charge cause they didnt find out shit ... and Now it runs... ( new gas) .. hopefully ...

Could be a bad connection in the steering column where the key goes in. I had a car (way back when) that would turn over fine, would sound like it was started and when I let the key go from start to run, it just shut down. I thought it was the fuel pump, changed it out, and had the same problem. After an afternoon of troubleshooting found that the connector that connected to the key post (or whatever you call the thing that the key goes in) had broken. I rigged something up to secure it and it ran fine.

It seems alrite now .. i been driving out of town and it runs great. But I felt like the steering wheel is a lilte bit heavier ..... I know it doesnt have anything to do with the fuel or gas or watsoever but hope somebody have the same problem can post in some good pieces of advice.
