2001 Kia Optima Stuttering and Shutting Off

Hello,

I have a 2001 Kia Optima with just under
133000 miles on it. During the last few
weeks, I had been noticing that the oil light
would flicker on for a split second a couple
of times a week. My oil change was
coming up and the car has had electrical
issues (air bag light stuck on, clock only
displays intermittently) so I just decided to
monitor it. A couple days ago, it started
stuttering briefly while I was driving. The
next morning it appeared to be running
smoothly. I got to work about 20 miles
away and as I pulled into my parking
space, the car stuttered violently and shut
off. I was able to start it up and move it
enough to get it towed and it still starts
and seems normal until I put it in drive or
reverse. Then it stutters a lot and
sometimes shuts off. The oil light has been coming on and staying on
longer while this is going on.

This car has had many issues the past year
so I'm going take it in to have it assessed
but was hoping someone might have an
idea of what it could be (if my description
is not too broad). It might just be time for a
new car. Thanks in advance for any info!
