My suburban runs rough surges and stalls when the motor is warm. It is like it is not getting any gas or has lost power. No check engine light comes on, and already changed the fuel filter, spark plugs, wires, coil and rotor cap. What else could it be?

Try a new engine coolant temperature sensor.

Even though the check engine light is not on your should run the codes to see what comes up

Here is a guide:
