Default 2000 B2500SE 2.5L Intermittent Power Shuts Off

I have a 2000 Mazda B2500SE 2.5L 4 Cyl, Manual Transmission, does this Model have a Camshaft Synchronizer? After changing a damaged fuel pump truck was running beautifully then died in the middle a street.
New Battery, Fuel Filter, MAF, TPS, EGR valve, IAC, Oxygen Sensors 1 & 2, Regular Belt, Bottom Pulley, Fuel Pump. Mini fuses all test good, have to test Relays but I can't find a Fuse Box Diagram for this model light Truck. Cleaned chasis ground. I'm no mechanic.

Problem started with intermittent inability to start. There was rough idling & hesitation before I cleaned throttle housing - changed all parts listed. Fuel Pump internal hose was damaged that resulted no pressure. Symptoms research leading me towards camshaft synchronizer or/& cam sensor.
Got a cheap Volt Meter to pursue electrical Open Line but this is a learn as you go without transportation now.

Current Symptom: Intermittent Power Loss, Cranks, No Spark, No Engine Light when key is in On Position, No RPM movement, No Power to Fuel Pump, Red Check Gauge Light,

Timing belt broke? See if you can pull back the top part of the timing cover and see if the cam sprocket turns when cranking the car. Watch your fingers!

Another sign is the way the cranking sounds does it sound even it does it sound like it speeds up in some points?

It could be a faulty inertia switch. There are videos on youtube about them. They commonly fail in fords.

He said no spark. Inertia switch wouldn’t cause that

Quick update, Truck turned on today after sitting 4 days. Didn't crank it, Not safe to drive since it will shut off without warning. making the No Start Intermittent.
