Ceased up?
I’ve got a manual 2004 Ford Ranger xlt, 4.0l 4x4.
I was driving at 35mph, in 4th gear, started losing power (wouldn’t accelerate any more)
put it into neutral and rolled into parking lot, stopped at stop sign, put it in first to get moving again then pulled into parking spot and as soon as I let off the gas all together the engine slowly died. Try to start again, turned over once but didn’t start and hasn’t started since.
1. Oil is good
2. Battery is new (changed recently)
3. Engine light p0301 (cyl 1 misfire)
4. No smoke, noise or leaks
5. Engine felt like it was rattling and wouldn’t sustain a steady rpm
took it to 2 mechanics, both said engine is seized, but couldn’t tell me more than that, and both only had it for about an hour.
up till now there were no issues, I’m at 138k miles and I feel like it couldn’t just give out like that. Any ideas?

Welcome to the forum
If starter motor can not turn the engine then it is indeed siezed
You can put a socket wrench on the crank pulley bolt and try to turn the engine one way and then the other to see if its a main bearing issue or a valve timing issue
Mechanics should have done this????
Only takes 5 minutes to do that
Several reasons an engine can seize up, in the 4.0l SOHC a cam gear could have shifted causing valves to hit pistons, causing loss of power and then stall, starter can't turn engine one way because piston is hitting against a valve, you could try turning engine the other way to see if it moves, if so then that's the issue
Spun main bearing, one of the crank shaft bearing's oil supply stopped, got plugged up or ???, when that happens bearing heats up and it is softer metal, it starts to spin with the crank cutting off all oil to it, so its getting hotter and hotter, this slows down the crank, loss of power, and eventually it will stop the engine from turning, it basically WELDS the crank in place, so it can not turn in either direction.
Neither of these are based on miles and either can happen suddenly, out of the blue
"Rattling" is often the description given of a valve timing chain issue on the 4.0l SOHC engines
And this is all based on your description of the sudden loss of power and that the engine is "seize", otherwise I would say you "ran out of gas", lol
