I'm not sure if I understand your original post correctly. Did the car act up AFTER filling it up? My car turns to sht about 1 bar below half already. I know not to hammer on it (not that I would on the streets) around people when the gauge gets to that point cause it acts up.
If it did act up on a full tank that's a different story. If it didn't on a full tank but did on a 7 gallon tank I will go with poor fuel pickup.

Well? How about an answer to this post.

oooh... TPS... I hadn't thought of that one. I will check voltage tomorrow. I can check voltage... just turn on the key and not start it. 
I am also thinking a bad ignition switch... but TPS does make sense. It cuts out all hell breaks loose. And it would wig out the EBCM...
And yes, Hippy, it wigged out with a full tank.

I ordered a new TPS and ignition switch... they weren't all that expensive... so a little PM could save me a ton in diagnostic time.
I still think the alternator is a bit suspect, but time will tell...

The ignition switch I have never done, but the whole column was redone and I needed a new key.

the TPS is easy on the LT1! you are right, no adjustment needed.
The switch is pretty straight forward... drop the column off the dash and it's right there.
Between them, they were only about $45. and that's for GM parts.

engine dies
is there a possibility that your engine ground is determined by your engine mounts?
move the engine either way in a turn, and the engine dies without a proper ground strap?

status update:
I still don't have a clue, but the loose grounds/starter wires as mentioned above are actually my next step. Unfortunetly, I won't be able to do anything about it until Sunday, at the earliest.
I have replaced the ignition switch and TPS, no change.
It sure is odd... but I am wondering if the motor mounts, at 163k miles have finally given up. I have newer ones, I can and try and swap them out...

i have the same problem with my 89', when i "kick it" around a turn the motor stalls, then as soon as i let off the gas and go straight its fine. it has happened multiple times with all different levels of gas in the tank.... i was thinking it might have somthing to do with the injectors, but im not posivtive i havent gotten around to changing them yet

Cmon Andy. You R&R'd the TPS and ignition switch?
Something is loose forward of the steering wheel.
So does the ALT make the noise continously? Or only when turning?
What are your voltage readings with & without a load?

Make sure that nothing is hitting the top of the Opti or the plug wires. IN other words think about a Cross talk of the Spark plug wires. Or the Coil wires that lead to the Opti. Is there something frayed with those wires??? Is there something that could get to all the plug wires at once.
The reason I ask this is I had a heat shield come loose and lean up against a Distributor cap one time. It only did it when I turned........When I found out what it was....at night time and fooling around with stuff.......it was like a light show with all the blue "lighting" coming off those plug wires at the distributor.......
See if an ignition wire of some sort has some how come in contact with a Header and has the insulation burned off. Now when you corner it leans against something grounded.
That is all I got....

Good idea... except I have the LTCC, which bypasses the opti's high voltage section.
