Well, I have done extensive searches on the TFI subject to see if that is possibly my problem, but it does not match up completely.

My car completely cuts out once it starts to get warm and then gets worse progressively. The voltmeter stays constant so I don't think it is a ground or 12V source coming loose. The motor DOES NOT DIE, but simply looses total power as if turning off a light switch and then back on a split second later. Could this be ignition related? I have a Crane HI6 box that has only been installed for 5 months, but the test light shows that it is fine.

I have swapped the coil for another just to test and that was not it.

I had the TFI tested at Autozone and it tested good. He got it plenty warm to simulate driving for awhile.

I am stumped.
