Car won't start, has problems turning over

Yesterday on the way home from work,
the car was not driving like it use to, I
pulled over and checked the oil all was
good..went to get back into my car and
start the car it didn't start at the
beginning but I kept trying and it
started it took me about 25 miles on
the freeway then out of nowhere the
car shut off, then a security light came
on.. I pulled over and called my
husband and tell him what's happening
to the car, my husband came to me, he
then pulled the codes from the car and
these where the codes P0330 and
P0446 and P0441 what can be the
problem I checked and there is no
water in the oil and coolant level is
perfect...
