Other times it's just short-term and veru intermitent. Has anyone found a solution yet?

that said i am currently having the issue of not starting on my 2000 bonne sle. I have tried tapping the starter to no avail, tomorrow in day light i intend to check the fuses as well as having the battery tested (tho)ump starting did not do the trick)
put the key in, it says "driver 2" so the key is being recognized (i think?) all gauges work just fine. Turn and you hear a strong "click" but nothing after just silence.
over the past year the fuel pump, fuel filter, air filter, mass airflow sensor, coil packs, plugs, and wires have all been replaced with new components. Any ideas??
EGR valve might be sticking open due to crud on the pintle and sliding neck--but mine would stumble and almost die unless I opened up the gas pedal a little as I came to stop.
How does it die? At idle? at 50 mph?
Stumbles? quick quit like ignition shut off? rolling feeling like rich choke used to do? maybe trans staying locked up as you slow down with jerks?
Does the tach go to zero as it dies while engine is still spinning?
When it won't start, check for spark with a spare plug laid on the engine metal with a spark wire to it.
Also try the Schraeder valve for fuel pressure (use a cloth to catch it or you might get covered or the car go up in smoke -- insurance value??? grin)
You're going to have to diagnose for fuel, spark, and air. Those are the three things it needs.

But I recall comments in Bonneville discussions that a higher than usual number of problems came from the computers for those two years. I can't check to see if you replaced the computer...

Also, it could be a fuel pressure regulator with a leaking diaphragm. That switches the amount of pressure at the injectors based on vacuum. You can check for raw gasoline in the line by pulling it off of the fuel pressure regulator (on front of engine on driver side with one vacuum line going to it--it will be shown on the vacuum diagram under the hood).
And it could be the crankshaft position sensor. With that the tach would drop to zero and be your first sign the engine is dyiing, because the engine loses ignition control to trigger spark when the position sensor fails.
People say splashing cold water on the crankshaft position sensor to cool it speeds up the restart if it consistently has to wait to cool before the CPS starts working again. It's behiind the edge of the balancer pulley.

I thought the CPS did not set any kind of code? That's what makes it difficult to diagnose using circumstantial evidence as to its being bad or not.

I would check the ignition switch carefully. I do not know anything about the physical arrangement of the parts on your car, but that ignition switch can have different contacts for different services. As it heats while the car's running, individual contacts can lose connection while others stay in contact. Heat, vibration, burning, can lead to the bad contact while running.

I am having the same kind of problems with my '96 bonneville ssei supercharger.
The pressure should be tested with the engine off and the key on. The pump will run a couple seconds and then shut off. The pressure should hold unless there's a bleed down from a leak or the fuel pump. Then the pressure should be checked with the engine running at idle, and then the pressure noted when the engine is accelerated causing the vacuum to reduce which lets the fuel pressure regulator up the pressure.
Second choice would be the MAF sensor may need cleaning.

But for others reading this, I'd like to offer a cheaper way to handle VATS problems where the security light blinks for 3 minutes AFTER the key is turned indicating it's getting a wrong reading on the resistance through the key.
The owner can identify the usually orange tube that has two fine white wires in it that comes from the ignition switch (not the lock) and goes to the connector on the firewall above the parking brake. Cut those nearer the steering column to leave some slack. Put in soldered resistors in series that add up to the resistance on the key chip, within 5% or so. Usually that will fool the TDM (theft deterrent module) into thinking the same key resistance is presence. This will cost a dollar or two for resistors from Radio Shack if you are able to do the soldering and locating work yourself.
The usual break point for the two fine wires is where the tilt column is flexed every time it's moved. The contacts in the lock also do wear and cause trouble along with a dirty key contact. So bypassing the whole mess eliminates the antitheft protections, but saves a whole lot of money.
Locating the orange tube with white wires inside that looks like a solid orange power wire is the hardest part. There are youtube videos that show some of this.
