Engine Performance problem
1999 Dodge Intrepid 6 cyl Two Wheel Drive Automatic 71000 miles

While driving at any speed the engine just dies out no hesitation at all. It usually starts right back up except for one time when I has to wait 10-15 min. Doesn't happen every time the vehicle is driven(very random). Could it be the MAF(Mass Air Flow Sensor)? I just replaced the Fuel Pump for two reasons one it's been difficult to start usually have to crank starter for extended periods. Then after it started stalling I hoped the fuel pump would fix both issues.

Now that your pump has already been replaced, with a new filter Im sure, another electrical problem may still exist. It should store a code(the reason for car stalling) in your engine control computer(PCM). I would use a scanner to check. You may have a crankshaft sensor or other problem. Thats the fastest most accurate way to check. If you have already complained about your car stalling, and the fuel pump was replaced for this problem, it may or may not be related. But bring it back, and have it checked. It's probably something else. The fuel pump replacement was smart, and at least you have a record of it's replacement. The fuel pump failure is the most common problem in any Chrysler car with mileage over 70,000 miles.

Replacing the fuel pump did fix my hard to start problem so that's great. But the stalling problem does still exist. I did scan the ECM/PCM and had perfect results. No trouble codes exist. Could this be a faulty electrical connection to a component in the vehicle? Do you have any ideas on which component could cause this? I.E. Bad ECM, PCM, MAF, Crankshaft Sensor. Would you diagnose by lightly tapping or jiggling connectors on each of these components and see if the car engine stalls?

Yes, you could try that. It's the first step, to do a visual inspection, checking for wiring problems. Depending on the type of sensor that is shutting down. If my car was shutting off, here is what I would try first. 3.0L speed sensor. 3.3L crank sensor, same for 3.8L.
Sometimes the manifold absolute pressure sensor(MAP) will cause the engine to shut off, but it usually starts, runs for a second than stalls, needing a tow job. In 88 every vehicle, that died, made by Chrysler would have no codes, and than you would have to start diagnostic procedures for a no code situation, and the 3rd time was lemon law, so a new PCM was installed, simply because it's internal checks were not picking anything up. The speed sensor was another problem, especially if there is any problem with your speedometer or speed control. Ok
