I was driving home today and as I was turning into the alley to my parking lot I noticed the car losing power. The rpm decreased gradually from 1200 to 0 in 1-2 seconds and right before the car died the "check gauges" light came on. I tried turning it on but it didnt work. The engine was turning but it wouldnt actually start. I let a minute pass and I started it again and it started, I drove to my parking lot and it died after parking it. The temp gauge was normal, the oil gauge was normal too but it was on 0 when the key was on the "on" position. The fuel was low but the light wasn't really on. Usually when its out of gas it just stops and doesnt start back up after. Is this normal for a low fuel situation?

 

Easy way to find out is put gas in and see if its stays running. I can't say thats normal as I have never seen it happen like that.

 

I'd lean more towards the fuel pump on it's way out

 

BolBol, it could certainly be the fuel pump. That's a fairly common problem with the Blazer and in fact with many GM products. Always check the easiest and cheapest things first. Which in this case is to put some good fresh gasoline in it. Try to crank the engine and drive it a while. Then buy a can of starter fluid to use next time this happens. If it cranks with a shot of Starter Fluid and then dies, it could mean the fuel pump is 'going out' or intermittently acting up before it dies completely. Have someone near the gas tank listen for the fuel pump 'run' for a 3 or 4 sec.s or so when the key is turned on but not put in the start position. Cycle the key on and off and you should hear it each time the key is on--not started. Of course, this may mean the fuel pump is running but not operating at the required pressure. Check Capt. Hook's previous posts on how to test the fuel pump.
This random engine dying could be so many things: a clogged fuel filter, an ign. coil going out, a Crankshaft Position Sensor going out or affected by heat.

 

In my 2000 jimmy I had a fuel pump issue where the fuel line in the pump that went from the strainer up to the electric pump pulled out from the strainer. When fuel got low it would start sacking air when turning right or braking. Also if you parked at a slight downhill incline on low fuel sometimes it wouldn't start. A new fuel pump fixed the issue. After I installed the new pump I started taking the old pump apart and found the line had come out. The line would sit about 2-3" higher than the strainer on the bottom of the pump and once the fuel level got lower than that it would suckered air and lose fuel pressure.
