My son in law had a similar issue with his 10 Ram 1500 with the 5.7 MDS setup.

Turns out when he had his oil changed the place that did it put on a different oil filter, it was substantially smaller than what was called for. We changed the oil and filter and no problems since. They seem to be sensitive to that.

Dealership wanted to charge him $1200 you change out his phasor VVT solenoid and lifters, I believe. There was a TSB on this and step one was change oil and filter to ensure it's correct and retest. They didn't even try that.

But his issue did throw codes, do you have any?

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
