ENGINE SHUTS OFF

1999 Mazda b3000

Electrical problem
1999 Mazda b3000 6 cyl Two Wheel Drive Automatic 125000 miles

My engine shuts off while I am driving my truck.
It does start back up after a couple minutes but after a mile or so it shuts off again. I had it at a repair shop and the computer hooked up to it says the problem is coming from the anti theft system. The ignition key has a chip in it, so I had a new key cut and programmed but it didn't fix the problem. The fuel pump & filter checked out ok. The strange thing is, in the morning after the truck has been sitting all night, it goes about 9-10 miles before it shuts down. After that it shuts off after a mile or so and continues to do so until I can get to my destination.
