Angry Reduced Engine Power, tried most of the repairs mentioned still nothing please help

2003 Chevy Suburban 1500 4X2
225,000 Miles, engine runs strong (when it doesn't have this issue)

Occasionally (sometimes over bumps) I get Reduced Engine Power and Check engine light comes on.
The truck gets so weak that at a Stoplight it will die out.

I have cleaned the Throttle Body...
Since that didn't work, I Replaced the Throttle Body.
Since that didn't work, I replaced the entire Gas pedal assembly...
STILL no fix Is there, ANYTHING I should try that helped anyone here?
I'm starting to get Desperate...

Maybe unrelated, Occasionally my aftermarket Radio Resets itself (like it the battery was disconnected) is this a sign of a bigger issue?
Thank you!
