I have an 89 5.0 AOD which lately after about 10 minutes of driving when you come to a stop sign shuts off. The alternator and battery are checking good. I just had the transmission replace in the spring. Anyone have any ideas what it might be?

Does the car crank but doesn’t start or will it not even crank?

TFI tester that anyone with one of these cars should have in the tool box.

I can vouch for the McCully Racing relocation kit. Did this on my Coupe and it fired right up and zero issues since I did it. I even reused my old TFI module with the Artic Silver 5. So now I have a new Motorcraft TFI module in the box for a back up which is fine by me.
