Luv my 2004 Saturn Ion 1 but.....

I am getting a little frustrated...2.2liter
Installed new windshield, alternator, plugs, ignition coil and rail, battery, fuel injectors, cleaned idle control module, cleaned throttle body,changed oil and added quart of Lucas, new air filter, took quart of granny fluid out, out quart of Lucas in. So as you can tell I like my Lil grocery getter and keep up on it's maintenance. However, while driving it has started like shutting down( electroniclly). All I have to do is turn ignition off, turn back on...no problem. I checked battery connections, tightened up fuse box bolts...I an at a loss for the problem....any ideas would be greatly appreciated. THANKS!!

 

Service Engine Soon light on?
Security light flashing or solid when driving?

Does the vehicle actually stall when this occurs?
I ask because you specifically mention turning the key off and then back on, implying the key is still in the run position before you do anything. So my question is the car still running when this happens and if so, does it stall if you do not intervene?

When the electrical fade out takes place, how is the engine running right before and during? Is there anything that you can do to trigger this behavior?

Is the charging light lit on the dash?

What was the rationale for replacing the alternator, battery, coil packs, and fuel injectors? None of those are routine maintenance replacement items though I guess you could claim the battery is if it's dead.
