Corolla 4wd sation wagon dies in acceleration

[pagravel_90]

I have some trouble with my car, I can drive it fine until, sometime, when I accelerate or go uphill, the engine stops then it will restart fine. this weekend I change alot of things and it don't changed anything.
Here's what I change in the last 2 days:
-timing belt
-distibutor rotor and cover
-plug wires
-plugs
-fuel filter

also I cleaned up the throttle body and try to adjust the spark. Now I'm cleaning the injectors. next I might look at fuel pressure regulator or gas pump but I want some advice, I'm tired of changing parts...
