5.7L TBI engine problem

I have a 1992 Chevy C1500 5.7L
When I start the engine..it runs fine, I get on the hiway, and it runs fine...
But...after its all warmed up, and I am stopped at a light in drive...the engine will give a miss every now and again, it recovers and runs smooth for a few...then it misses a little worse..smooths out and idles fine for a bit...this keeps on happening until the engine cant recover and it stalls.
I throw it in park and she fires right up....
This is what I have done so far...with no results

New:
Fuel filter
Plugs gapped to .035
Wires 8mm Autolite
Cap and Rotor
Temperature sensor
Thermostat

I have cleaned the throttle body with Valvoline throttle body cleaner
Removed and cleaned the Idle Air Control valve
Checked for vacuum

Any ideas?

A good place to start it by having you codes read.
