Catalytic converter could possibly be plugged. I had that happen to a Blazer where the core turned sideways blocking the exhaust flow. It would run fine at normal throttle but hit a wall at 4,000 RPM if you floored it. After replacing it everything was fine.
its easy to check there's videos all over YouTube to show how
your symptoms are basically identical to these too!

if you have fuel trim lean codes it a fuel supply problem
if you want to rule out the cats...take the pre cat o2 sensors out of the exhaust to allow the exhaust stream to bypass the restriction. It will be loud but you will have full power if the cats are the problem.

Facebook groups are useless. Someone will tell you you need to put air in your tires to fix the problem.
