Do you have the box mounted directly on the firewall or do you have it mounted on the factory stand-off bracket? The bracket allows airflow behind the box for better cooling.  A bad coil can get hot and shut the car off. Once it cools, the cars could start again.

Does the car start right back up once it dies? You need to do some testing when it dies the next time. Check that you have power on the blue wire that comes from the ignition switch. Test it on either side of the ignition switch connector. Wiggle the connector around and make sure the connection is good. If that tests ok, move to the bulkhead connector and test on both sides of it. Move your way to the ballast resistor. The blue wire should have power in the "run" position.

Our resident GURU Chryco Psycho often suggests checking the reluctor gap in the distributor under these situations
Gap should be .oo8 between the pick up & reluctor Use a non-magnetic feeler gauge for this, or unplug the distributor before checking the air gap. The pickup coil should check with 150-900 ohms of resistance

Heat is a killer for electronics, wouldn't hurt to use the bracket for mounting.
It allows airflow around the ECU.

Here's 1, I'm sure there are many others.  Some people make their own, simple sheet metal with a couple of bends.

This goes back to the late 80's. When my orange box started to act up (play up) the car would stall and not re-start until a cool down period. It was replaced with a black one and running fine since.

I use the Rev N Nator with their recommeded Accel distributor . https://pisuladevelopmentcompany.box.com/s/poi72hxr32fn7zayvn456oand2v0nkzh
Their website now says they use a FireCore distributor.
It does well and was an easy install other than the wiring connection to the dual ballast resistor I had to do .

Currently using MSD 8222 coil, have the Rev N Nator coil also.
I was in the process of installing the MSD 6AL , had installed the MSD coil, then switched to the Rev N Nator and as long as it's running well did not want to switch coils.

I am sure shipping is too expensive , I have a brand new MSD 6AL box and MSD distributor  for 440, although 6 weeks ago I could have sent it back your way with my sister who was visiting from Tasmania.

If you might be interested in the MSD system for 440, I can check shipping costs.
Just saw on another thread you had a bad experience with MSD ready to run, .
Your trouble now is with the 340 , is that correct? Thought from your screen name was 440, .

I am in Texas, sister in Tassie.
The MSD 8222 coil can be mounted in any position as it is epoxy filled, mine is mounted horizontal.

Yes, I am using the dual resistor .
