Losing all power on acceleration

New here in need of thoughts or opinions. I have a 2005 tundra with a 4.7 L and the problem I’m having is when I go to accelerate have to do it very slowly or the truck basically loses all power for a few seconds, RPMs drop, spits and spudders then the gas pedal stops working, you can Press the gas pedal to the floor and absolutely nothing will happen for a few moments until it kinda revise itself. Gets worse the longer you drive. Any ideas what it might be???

 

It was throwing codes misfires so I’m not sure exactly which ones and also cat efficiency below threshold bank one and two I think I’ll have to double check. I did my catalytic converter’s just about a year ago got new ones but it never fixed the problem. I think I’ll try my injectors next thanks for the advice
