Sounds like it is missing?!

I posted once before on this, thought I would give it an updated shot at some resolution.

3rd trip in a row headed up into the mountains...I am not yanking anything but have a full load in the bed. Start to crest the hill and I will hear a short burst of a sound like "PSSST", and feel the truck lose power just for a second. This last trip, it happened for 3 spurts in a row. I have not gotten back to the dealership to see if any codes show up this time, but the last 2 there were no codes.

All 3 times, I have not been really pushing it, maybe 2500 rpms.

Maybe bad diesel? I wish I could figure it out, doesn't seem right, it had never done it in the previous 75,000 miles.

Thanks for any help or ideas.

I would suspect a boost leak.Do you have any idea what your boost is when it happens?Have you had a look at the CAC hoses lately?

CAC tube boots were replaced due to oil leak 10K miles ago, CAC looks good to me, but not an expert at all. I don't have a boost gauge, didn't come on the '03, and I have not added one. I will when I get my 5er...if I keep this crazy truck!
