Yeah that puzzles me since you have:
excellent grounds to the engine, body and ign coil
NEW cap, rotor, plugs, wires, coil, MAF, engine speed sensor(?) and other
new components.

if the engine is running too lean, that might create some misfires.
maybe your mechanic will catch the problem now that it is dying out more
often.

hmmmm "brownish smoke out of the exhaust"
don't forget to get that exhaust flow tested. maybe a clogged exhaust??

Yes generally if the ign switch is bad the idiot lights will not light up
when the engine stalls, or the lights go out while cranking over the engine.
Although on my '91 Passat when my ignition switch was going bad some
components worked and other didn't. I could drive but not operate my power
windows nor hear the radio. ODD huh? A new aftermarket ign. switch died in
about a week's time. My rebuilt one at least lasted about 6 months, but the
dealer's switch has been good for over a year so far.

guessing here again!
good luck,

Also the battery is good. Yesterday when it was dying I kept finagling
with the key and it would move the RPMs slightly, making them fluctuate
slightly....if the ignition switch was bad, wouldn't the dashboard
lights not go on when it stalled?

The misfire codes were PO300, 301, 302, 303, 304...in any case
yesterday getting on the highway the car was beginning to die and then
it backfired twice...brownish smoke out of the exhaust, died, then, got
it started, died aboout 100 yds. later, backfired while trying to start
it but this time under the middle of the car, and white smoke came
billowing out on the side..sounds like it blew a hole in the
exhaust...able to restart 5 more times for about 50-100 yds. each time
and was able to finally get it off the highway. The past couple of
days whenever it's died and you finally get it restarted there is
always a huge smell of gasoline, kinda like it smells when and if you
flood a car. My car then had to be towed to the mechanics.
