Chevrolet Tahoe LT my 1999 chevrolet tahoe loses power after

This answer was rated:

my 1999 chevrolet tahoe loses power after I've been driving it for awhile. I press the peddle all the way to floor and it does nothing, I can pull over and turn it off and restart and go for a few minutes and it does it again, why could this be happening?

this also explains
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
Hello and thank you for using JustAnswer. My name is XXXXX XXXXX I will do my best to help you with your Chevy problem.

Do you lose power for accelerating away from a stop? Do you have any other symptoms when this occurs?

If you stop and it will take off fine but will start to do this again within a few minutes.

This sounds to me like you have a bad ignition coil. A bad coil can heat up and make the engine act just like it is starving for fuel. I have experienced this on my own vehicle.

Another possibility is of course a failing fuel pump. A pressure test can be done to confirm this. Connect a fuel pressure gauge to the test port on top of the engine and take a reading. With the key on, engine off, you should have 55-62 psi. If the fuel pressure is lower than specified, replace the fuel pump.
