Believe it or not, I had an S13 that would turn off if I didn't hold my foot on the throttle. I took it to my mechanic to see what he thought of it and he adjusted the idle speed. Afterwards, the car stayed on by itself and idled at the proper level as well. I didn't think that would be the cause of my issue either but, it's worth taking a look at. If I were you, I would actually be relieved to know that the solution to my problem was as simple as adjusting the idle speed.
