I got a 03 slt 4x4 auto 4.7 with 312k original motor and trans, maintained really well, recently it’s developed a stalling issue.
It started one day when I left a gas station after filling up, I was accelerating to pass someone, the truck downshifted fine and the torque of the 4.7 kicked in, once it got past 3k rpms the truck shut off and lost all power, I couldn’t start it in neutral I had to pull over and put the truck in park then turn the key off and go to start it. Fired right up and went on with my day, that same day it did it again while merging onto a road, same process of shutting off the pulling over to restart.
It does it on the highway while passing too, I replaced my fuse box due to my headlights and taillights not working and it seemed to have fixed the issue for a couple weeks till the truck stalled while cruising at 100kmh I wasn’t on the gas and it quit.
Now with winter here, when I cold start the truck, it won’t stay idling for more then 2 minutes without stalling the same way.
I have no CEL at all, I hook up a scanner and there’s nothing stored in the truck, I’ve seen a couple threads here with similar problems but no follow ups from OP.
Any help is much appreciated I’ll update as I figure it out

Its fixed, was bad coils, replaced them with NGK coils and replaced plugs with oem champion copper ones, truck runs great now!
