My 1992 chevy s-10 blazer, starts, but dies out when in gear.

I would try another Dist cap or clean and inspect the one on it.

Check for fuel pressure and check for spark during the no start condition. Also check the crank sensor, it is located behind the crank pulley mounted in the engine block on the 4.3 L engine
I hope this helps.

The problem is in the idle air control motor. It is mounted on the throttle body with two bolts, you can pull it off and make sure it is not caked with carbon also check where it mounts on the throttle body and make sure it is not caked with carbon.

if u see check engine light then there is a fault, probably idle solenoid ,wiring , ECU

I had the same problem but not with the popping sound. Try checking your vacuum hoses. My problem was with the PCV Valve elbow. It is located under the air intake hose.
