Stalling Vehicle

[SilvrGrandPrixGT]

I have an 01 Grand Prix GT. Recently, I have had problems with the car stalling randomly. It doesn't happen every day, but it may happen 3-4x a day. In town, on the interstate, wherever, it will happen.

I took it to AZ because my "check engine" light was on. They said the Mass Air-Flow Sensor and the Camshaft Sensor were bad. I replace both myself and still am having the same issues. I figured this would have taken care of the problem.

I also had speculations that my fuel pump may be bad too...or going out. Does anyone have any other thoughts/ideas that may be the issue??

Fuel pump could be causing the issue, I would also replace plugs, wires and probably coil packs.

Thanks! Actually, I'll probably start with those, since they would be less costly. If I remember right, I replaced the coil packs on a 97 Camaro I used to have (3.8L too) for a similar problem. It had just been so long, I guess I had forgotten.
