I have an 83 Mustang that when it gets warmed up it shuts down
The car starts just fine, it's after it has been driven for a little while that it shuts down. If you let it set for awhile it will start up and let you drive for a little ways again, then shuts down
Could be coil.
Also could be the TFI (Ignition) module.
