Plus, posts in ALL CAPS are hard to read so most people skip over those posts.

Sounds like your starter could be bad. Works okay when it is cold, when it heats up it fails.
 
This is assuming of course, that your battery connections are clean without any corrosion, as that adds resistance.

chocking out and back-fireing when i try to give alot of gas pedal by wh7952

Over the last month my 99 5.7 4WD Tahoe has been giving me problems accelerating when I give it a heavy foot. When I hit the gas down it loses acceleration almost like it's being starved of air or gas. When I hit the gas the engines just bogs down, begins to hesitate, and will not accelerate. kinda like when you have a dirty fuel filter

Check your fuel pressure. Could be a failing fuel pump.

I unplugged my mass air flow sensor and the truck was a new truck, ran scary fast and had so much power like it was a new truck. Is it safe to run the truck with the sensor unplugged untill i get a new one installed?

I doubt it. It will set a DTC and probably go into a fixed fuel/air map that is rich to prevent engine damage. Probably why you're seeing/feeling increased power but have you checked mpg?

I just noticed significant drips on the garage floor coming out of the front differential....couldn't pinpoint where. Am I in for a big bill? Should I go to a regular mechanic or a transmission place?
