Well either a plugged fuel filter or a weak fuel pump. Do the fuel filter first. It’s easier.

May not be but check throttle cable, linkage all the way to motor.  
May not be opening all the way.

Too much back pressure in the exhaust system is possible. Sometimes debris can get in the exhaust. Mice and critters can make nests if the vehicle was sitting unused for a while. The muffler could be falling apart internally, or the cataylitic converter can be bad. Is “check engine” light on?

On this truck, the check engine light won’t come on for a plugged converter. Considering that it coincided with a change in exhaust tone, that’d be what my money is on.
