Chevrolet Camaro Electrical Problems

in Chevrolet
I have a 97 Camaro with a 3.8 and the car keeps shutting off while I am driving with no warning.It doesnt have any warning and its ddriving me nuts.Took it to the shop and had to fix some mickey mouse wiring it had and make the alternator self excite.Thought this would cure the problem but no it didnt. Could someone lend some advice please I can't afford to keep dumping money into if no one is ever going to be able to figure it out.The dealer wont touch it due to the wiring problem it had.Thanks

Thanks Barbara
Is there a fuse or relay just for the low beams? How can I tell if it is the headlight switch or the multi-function switch on the column that has the turn signals, wipers, and cruise control?
Other electrical items works OK.
Is there a fuse for this or where is the remote receiver?
thanks
If I sit there and turn it, it might start in 2 minutes. It might not start for 30 minutes. It will crank and crank.
I go and wait 30 or 40 minutes. Come back. Starts just fine. It might make it home. Sometimes it does. Sometimes:
I drive to the intersection and it dies at the red light. It will not restart. Push it off the road. Try to start it. No. Wait 40 minutes, come back. Starts, drives home fine. But when I am going to park it, 3-pointing, it stalls out again. I sense it is stalling out. I give it some gass. It seems to cough a bit, like it's sort of fighting stalling, but dies. The next day it will start again. Bit dangerous when it stalls coasting on the road or highway though.
If anyone has experienced this. Please let me know.
I took it to the shop, but they diagnosed me with a dead battery (after initially telling me their batt/alternator test My battery and alternator were good.) Then that I had a drain of 7Amps to my stereo when the car is off, which was their final diagnosis, though I told them the car does not run out of juice overnight.
Battery:
I have done tests on power with a voltmeter, seems within specs there.
Could a parasitic drain do this? Without draining the battery dry overnight?
Fuel: Can hear the pump, also there is a squirt-tester under the hood. Always has lots of spray. Even when car is just cranking and not starting.
As for fuel and air, I don't know really how to test these, or if they could cause this sort of problem.
What could cause an intermittent stall and intermittent not-start, seemingly based on nothing but time. It seems unlikely it is a overheating issue, because 30 minutes and not starting in Penticton makes the engine pretty cool already. And sometiems it restarts after driving a long distance in summer just fine. Also, sometime if I just turn it, then turn it, then turn it, it suddenly starts. But not usually.
It does not seem to die when it has gas on it. Basically when my foot is off the gas.
Thanks.
