What causes intermitten stalling at slow speeds?

Why does my car stall at highway speeds?
The engine may start and idle fine, but run out of power or even stall at highway speeds. If the engine starts right back up after stalling, the likely cause is low fuel volume delivery because of a weak pump. If the engine is running normally one minute, but suddenly quits, loss of ignition may be the problem.
Can a stalling engine be intermittent driveability?
Intermittent driveability problems of any kind are always a challenge to diagnose. When a customer brings you a vehicle and complains of a stalling problem, you may not have much to go on other than their description of what’s happening and when it happens.
Is there check engine light for intermittent stalling?
Many times, there will be no check engine light and no fault codes to give you a clue as to what might be causing the engine to stall. So the trick to diagnosing an intermittent stalling problem is to catch the vehicle when it’s acting up — and that rarely happens when you have the vehicle in your shop.

What do you need to know about intermittent stalling?
And if there are no pending codes, hard codes or history codes in the vehicle’s computer to give you some direction, you may find yourself guessing at a diagnosis. Every engine needs three things to run and idle smoothly without stalling: a correct air/fuel ratio, sufficient idle speed for the idle load, and a good spark.
What causes intermittent stalling on a Ford Escape?
Ford has also issued a recall (04S13) for 2001-2003 Ford Escape sport utility vehicles with 3.0L V6 engines for an intermittent stalling problem. The stalling typically occurs while decelerating at speeds below 40 miles per hour. The problem is caused by the calibration of the idle air control valve and evaporative emissions system.
