Exclamation SC3xx starts then dies, please help!

Before this is read, yes I did look up answers and I found nothing, and beware the wall of texts!

Hey guys, I have a 95' SC3xx and I've been having this issue with it since yesterday...
I went to the gas station and it was pouring pretty bad, I was almost basically on empty so I put 10$ in but I used 93 (instead of the 89 I normally use). Here is where the problem came up, when I turned the car on it started up immediately but just as quick as it started it died. I tried several more times to turn it back on thinking the gas wasn't through the fuel lines so I hoped it was just cycling through, but no, it kept turning off. Eventually I got it to stay on for about 5 minutes but the second I took it out of P, it died again, and afterword wouldn't start unless it was in Neutral. I took it home, waited for it to dry, then started it back up, it ran, and I left it running for several minutes before trying to go anywhere but as soon as I did, bam, died again. Now I'm honestly worried, it's been a day and still the same problems, and the car has been dry all day, what do you guys think the problem could be? Bad o2 sensor? Wet wires? I'm worried bad, it's my daily and I need to get around ..

My first guess would have been the fuel pump ECU went out, but I'm not so sure. You may want to try the 12v fuel mod just in case. If it doesn't work, hopefully someone will know what's wrong.
