96 grand am--familiar problem?

car starts, then does'nt. replaced plugs, wires, fuel filter, fuel pump. I think through this forum and some investigation I have narrowed it down to lock cylinder/ignitionswitch/passlock system. However the car also will die when driving down the road, then start again after a few tries. Before I spend more money I would like to know of the stalling while driving is a symptom of the lock cylinder, and the rationale behind it. Thanks for any insight.

sounds like a injector is clogged or a bad pump.get them both tested at a shop for about 45.00
