Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

have you changed the fuel filter

SOURCE: I have a 2000 kia sportage with 150k miles.

This sounds like the fuel pump is going out. Was the filter plugged?

It is sometimes difficult to determine exactly what is wrong with the 7.3L engines. Many times it is hit and miss for the do-it-yourselfer. It sounds like you are getting enough fuel at first and then fuel is being constricted. You might want to try changing the fuel filter. Sometimes debris becomes lodged in the fuel tank switching valve which would require cleaning the valve or replacing it.

bad fuel pump or filter, bd spark plugs, bad coils. check the fuel pressure, check to see if th plugs are black r a brownish color if ther ar black then replace them. get a vol tester and test your coils.
