Still sounds like a transmission problem. Especially if it is revving up that high on RPM's and going no where. Sounds like slipping or something in transmission. Could be torque converter.

Why does my 1995 Sonoma 4.3 bogg down when I give it gas or passing gear?

Depending on the mileage, the most common problems are low fuel volume due to a restricted fuel filter or weak fuel pump. The other possible cause is a partially clogged catalytic converter, which puts back pressure on or "boggs" the engine when trying to accelerate.

you could have many different problems . your fuel injectors could be clogging up / your fuel pressure regulator / your fuel filter/ your throttle position sensor etc. do you have a check engine light on ? if you do when you take it to your mechanic he can use his obd scan tool to read the code and then take it from there

1992 gmc suburban has no power and bogs in cold weather

You need to perform an OBDII diagnostic test and look at the stored faults. Sounds like a temp sensor or Mass Airflow Sensor. Also dirty air filter needs to be changed every 40,000 miles. be sure to delete stored faults and recheck OBDII periodically for new faults.

1992 GMC Suburban not shifting into OD, Transmission Modulator?

The shift down linkage on the carburetor below the gas pedal cable might need to be adjusted to increase the hydraulic pressure on the internal clutch plates in the transmission it shows you how to do that in a car manual.

1998 gmc 4.3 starts up but loses power 3-5 mins later,will restart and run again for another short time,fuel filter has just been replaced.

Install a pressure gauge, start and run 3-5 minutes and watch the pressure. You should see the pressure maintain as it did when first started. If it begins to drop, the fuel pump has gotten weak and is starting to fail.
Let me know what you find.
