1997 Daymon Daybreak no power need help

Hello All

I am in need of so desperate help. I have a 1997 Daymon daybreak with the Chevy 454 motor. We are having an issue with loss of power . We changed the fuel filter, checked the Airfilter, performed a tune up, checked for vacuum leaks and engine codes with no luck . The unit stumbles and hesitates (worse when it's cold) apon acceleration . It has no power up hills however we can get to 65mph plus on flat ground. Does anyone have any ideas as to what I might try . Thanks for all the help in advance

    Also the guy working on it for me says the fuel has an odd smell to it ?

    Also is there a way to test the fuel pump to determine it is indeed bad before we drop the tank ? If so what psi or something should Inbe looking for and how to test it?

    Hello Thanks for the info . When it's cold even when I first step on the gas it does stumble . It does seem to get better once the engine is warm . I am pretty sure the engine even popped couldn't tell if it was exhaust or intake . It only did this when it was cold though
