Message Hi i have a 1991 300zx twin turbo runs well always have been
well kept.

Two weeks ago i had a problem with the car shutting off on
me if i drive it more than 25 minutes then it wont start for
about 10 mins it then will start up and run fine then shuts off
again if i continue to try and drive it.

Fuel is fine, changed ptu, cas, new ignition switch. If i leave
it and let it sit for a while it will run and wont shut off unless
under load(while being driven). No error codes from car ecu
nor when it was put on the computer but cylinder 3 is weak
and 5 no fire but the car runs very well with no loss of power.

I know my z history I have owned this car for over 5 years and
i have been in the nissan family from i got my license but cant
figure this one out please help
