So one night I was driving my car and as I came up to a stop light my
car died.  It took a couple times to get it started.  Then it was fine.
Then a couple days later I was driving my car then all of a sudden my
check engine light comes on and the car just dies.  That day it started
right back up.  The next day it does the same thing.  It's been an
ongoing process.  Some days when I drive it the check engine light
comes on and it will either start right back up or I have to let it sit
for quite a while before it will fire back up.
I took it in to have it fixed.  They replaced the coil, spark plugs,
and some valve gaskets.  That was not the problem.  The check engine
light came on and was doing the same thing.  So then I got a main relay
for my car and replaced that.  It ran fine for a small while then the
check engine light came on again.  So I'm pretty much clueless as far
as what the hell is wrong with my car.  If you have any ideas of what
it could be that would be great!
