If your 99 Chevy Suburban runs smooth, but going up hills it loses almost all of its power and only goes 40 to 50 miles per hour, check the distributor. The cap might be broken or cracked.
I have an 88 EFI truck and it loses speed (not necessarily power) going up hills because it is a manual transmission and it is geared low... and also if you are in higher altitude. Mountains ect..the electronic fuel injection may need to be redone.
Short answer is no. There is however a technical service bulletin out for the speedometer needle shaking at 60mph and above, as well as erratic operation. It refers to check a ground that is on the drivers side of the engine, as it loses connection. It is under the intake manifold, towards the middle of the engine.
cat converter is getting plugged
Perhaps catalytic converter plugged?

It loses power because going uphill is harder then going downhill therefore causing it to use more gas and then making it lose power bit by bit.
