If it stalls in drive but not reverse, it could be a transmission problem.
Is the check engine light on ?

    One possible transmission problem could be the torque converter. In years past, GM had a major problem with a sticking lockup torque converter solenoid. The transmission acted like a manual shift with the clutch engaged. Can you tell if it acts like you are turning the key off, or more like you popped the clutch on a stick shift model ?

SOURCE: 1989 GMC 2500 5.7L - engine surges and stalls at idle. Loses power at cruising speed.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

Spray the intake with carb cleaner to find the vacuum leak. Check where the EGR mounts and the throttle body gasket sense you had both off.

I had the same problem. There are two water temparature sensors located on the housing where the top hose conects to the head. the top sensor is for the temp guage on the dash and the one below is the sensor that needs replacing.

SOURCE: truck stalls when I give it gas

It sounds like they have got the distributor out of time. You will need to adjust the distributor. That is what it sounds like.

It sounds to me like you replaced everything but the most likely cause of a stall while driving...The crank sensor.
