My amazing 1999 F150 4.8 V8 2WD ExtraCab with 235000 miles.
Runs smooth as a sewing machine.

The truck just started with this issue
driving normal at any speed
the engine dies suddenly
the theft light is blinking
will not restart

Once this happened when my battery was dead and had to be replaced.
Replacing the battery solved the issue.

The battery is 12 months old and turns over the engine with lights on (as a test of the battery)

Today the truck would not start and the Theft light was blinking.
Just a few minutes ago the truck did start but the Theft light is still on and blinking.......

Any assistance resolving this issue would be greatly appreciated.
