Typically when the BR goes bad, the car will start every time, but will die when the key is released to the run position.

I have had some not start until the key is released as well.
Same problem, just on the opposite circuit. (the start circuit of the ballast)
 
A bad fusible ignition link, or bulkhead connector, will/can pass voltage but may not supply enough electrons. Give yours an inspection.
For testing purposes, you can run the coil plus side jumped straight to any battery voltage.
A 4-pin ECU can also be jumpered straight to battery voltage
A 5-pin will overheat, so not recommended.
The ECU wants to see a minimum 9.5 volts and needs a solid ground.
