WHY DOES IT CUT OFF WHILE I'M DRIVING?

1987 Mazda b2000 • 175,000 miles

I have an '87 Mazda B2000 truck and it will cut off on me while I'm driving it, in motion with my foot on the accelerator. It takes a while to start it back up but it's getting harder and harder every time. There's fuel in the fuel filter and I have a brand new starter on it. What could be the problem?

Start with a fuel pressure test to verify fuel pump pressure is sufficient.

This truck has a new starter, ignition coil, fuel filter, and fuel pump (fuel pump most recent) and it is still doing the same thing.

I had one doing the same thing as it turned out it was the ignition switch cutting it self off and on
