Guys, just wanted to add my experience here.
Same problem with a 2020 1500 Laramie. About a year ago, the dreaded stop and click after about $2 worth of gas. Drove me nuts as it was taking forever to try to fill the tank. Tried holding the nozzle different ways, lightly squeezing the trigger, but just kept stopping. Ended up only ever half filled the tank. Read this thread and thought I sure ain't paying for a new tank. About 2 weeks ago I had to do a long journey so spent about 20 minutes filling the tank to the top. Stopped off to put more gas in after a couple of hundred miles and I was getting $6 worth before it clicked. I wondered if it was a different nozzle or flow rate or something but hey $6 is better than $2. I'll take it.
Next fill I was getting $12 before a click. No idea why. Was low today so put $58 in to fill the tank. Went through without a click. Same pump I'd used before with a $2 click.
No idea what happened. Hopefully whatever it was has cleared itself.
Ooops, sorry just noticed this is 4th gen not 5th
