Asked by Mar 21, 2015 at 09:30 PM about the 1979 Porsche 911

Question type: Maintenance & Repair

The car will fire up and run good. I can drive it home no problem, but after a couple hours
of driving (give or take), it just dies. I can take it home, unplug the battery and plug it back
in a little while later and it will fire up again. It doesn't sputter and it's not a fuel problem.
The fire just cuts off completely without a sputter, pop or anything.

Check the "brain" box under the driver side seat. My 87 did the same thing, jsut quit. Changed the brain box and we're good.
