Manual Trans. Black smog on pipe. Had time belt changed a month ago. Was runing fine until now. It starts fine and drives fine, but when hot it will loss power about 1p to 20 mins after running, you need to gradually reduce the rpm, if you press the pedal won't get you power, so you will be reducing the speed until some point motor will stall. Won;t start again until cold.
Have cheked O2 sensor 0.7 volts, Map 110 Hz Working fine. EGR valve disconnected and vacum line plugged. Vaccum intake tested OK and steady.
Also some knocking sound when accelerating in 1st or 2nd speed.

just because the engine is in-line doesn't mean it's an L-head. it is not an L4. it's over-head valve. anyway, if the truck is carb'ed, i'd check that.

Suggest that you check the fuel volume and pressure when it is warm and beginning to run rough. Is ti carbed or is it injected? Same same. Could be a failing fuel filter, fuel pump, or if it has the two-stage pumps, the fuel strainer between the tank and the high-pressure pump.
Good Luck
