A common issue with the later 90's chevy was an ignition tumbler going bad. So, where you put your key in to start the vehicle--this part needs replaced. One I seen actually stuck in the starting position and burned up the starter before power could be shut off to the vehicle.
Sounds like it could be a dirty or faulty idle air control valve.Take it off and clean it with a wire brush and a non-chlronated brake cleaner or replace it with a new one.Make sure you reset the computer after cleaning or replacing the valve.

I'm assuming that by turning over, you mean that the engine fails to turn with the starter . Check your battery for 12v and make sure all connections are clean and secure. If battery has less than 12v charge it and check the charging system after re-starting. Lights and radio do not pull the same amperage as the starter and may not tell you much about battery condition. If you have full battery voltage, check the starter for 12v at the battery connection and the small (trigger wire) for 12v with the key turned to start position. If you have both, likely starter has failed.
replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump
thanks, thats what i thought it was the fuil pump.
