Engine stalling while idling. Rough idle

[xboxrox]

Does your truck have wire type fusible links coming off the + battery terminal that supply 12V to the wiring harnesses; maybe a bad wire or loose connection..? I posted plenty photos of "fusible links" check those photos

Only recently have I learned that the big red cable on the + pos battery terminal is ONLY powering the starter motor ~ smaller wires off the battery power all the other stuff ~ themz is what needs checking to be sure 12V power is being constantly supplied ~ some guys hate Scotty Kilmer auto mechanic on YouTube ~ maybe google search him diagnosing a similar problem as yours
Good Luck & Enjoy the Fixing
