Attention: TDR Forum Junkies 
As title of post says losing power, no codes, fuel filter changed, 2nd one in 2 weeks 1st one changed for pre trip maintenance, I did not see that filter myself.
"Rest of the Story" this past week we have been using our 05 Dodge 5.9 dually, in support of a Southern Baptists disaster relief ministry mission trip, to Perry Fl to do some tree & debris removals following the "visit" from hurricane Idalia this past August. Getting better there still some ongoing work probably into November.
Drover over last Friday, from Gautier MS about 350 miles there, returned last night, drive over and drive in town while there no problems, we have a trailer we tow loaded with tools, supplies, and a small tractor withgrapple to move debris, approx 10K# load. We refueled at a small truck stop before getting on I-10 W from US-19N (Mobil Fuel) quite a few OTR trucks so should have had good fuel.
We made it about 200 miles in trip and noticed while passing, and up grades now power and slowing from 70mph while on level grade to strugging to maintain 60 mph, we made another 80 miles "babying the truck", discretion being better part of valor before getting on the bridge/tunnel into Mobile AL we stopped and changed the week old fuel filter changed before the trip over.
The filter we removed did not look bad, at all, bet just to meet thattroubleshooting we installed the new filter. Little to no difference, no WIF light, no codes, only oddity when I opened the fuel canister drain nothing came out, so I susped some crud in bottom of the bowl blocking that.
Truck has 97K miles on it at least 1 owner prior, basically a stock truck odd part for me acts like low fuel pressure marybe from tank to CP3, missing and stumbling even at level highway speeds, the oddity though when pressing APP to floor for more power, I'm getting black smoke that normally would be indication of low boost.
Not my personal truck so no gauges in it to assist in dignostics, I have a edge monitor on my personal 06 5.9 3500 4x4 dually, I plan to plug it in and seet what that might reveal, no EGT probe on it but I should be able to see rail/boost/IAT etc. paramatersvia OBD-II port.
Not really looking to do "part swap trouble shooting, on my GM K1500 with 6.5L Detroit diesel when I suspect "snot plugged sock" in tank or weak/no output from lift pump to injection pump I rig a temporary pressure gausge on the fuel filter water drain, open drain valve and go on test run and read output pressure, would same concept work on a Dodge fuel canister drain?
Any other thoughts beyond low fuel pressure to CP3/contaminated fuel, I pulled MAF sensor from air box it looked cleanjust for another trouble shooting point sprayed it with MAF cleaner spray,again we had no codes just looking for other sensor possibilies if fuel checks do not tell us anything.
