Intermittent power loss on long uphill runs

I have a 2004 140" passenger van with 90,000 miles. In the last 2 months on long (10 mile ) uphill grades under constant load I'll loose maybe 5%-10% of my power about every 15- 25 seconds, for maybe 3-5 seconds, and then get it back. While this is happening I have constant pressure on accelerator. My fuel millage is 22-23 mph. Thanks for any feedback.

The turbo resonator can be a problem on T1Ns; it's very common in Sprinter-based RVs for them to fail. It tends to crack along the mold seam.

Is it on all gears? It looks like You don't have that many miles on Yours but see if it does it under load on all gears too.

My symptoms were exactly as you described, failed stock resonator was the culprit. Went with the Dorman unit, no issues 40,000 mi later
