Please elaborate about "starting every few weeks." For example, Start and let idle or start and drive vehicle.

Fuel filter replacement??? What brand, proper filter? Air leak? What style hose clamps used???

Check fuel injector wires, known to chafe on fuel hardlines.

Did I miss it, what engine???

2015 6 cyl filters changed before factory requirements. Problem occurred before any filter change and after oil, air and fuel filter changes. Factory clamps reused on fuel filter. Fuels filter was Mercedes. Start every few weeks ad run for 5 mins approx.

My 2016 RV (6 cyl diesel) has had the same symptoms once since new. It had set about 3 weeks but I had started and ran the engine for a few minutes during that period. The next start +- a week later it stumbled/missed and would not accelerate for maybe 30 seconds then normal. ( I know technically a diesel can't "miss") Now have 52K miles and it's never repeated....
