2004 Lexus RX 330 slows down dangerously when going around a curve or even when accelerating onto the expressway it will not accelerate. It does this randomly. no Mechanic seems to be able to figure out what the problem is.

You probably need a better mechanic. What specific troubleshooting steps have been taken so far? Has a full system scan been performed? Live data recorded while the problem occurs for later analysis? Checked fuel pressure? Checked exhaust system back pressure? Checked spark plugs?
You did not provide the vehicle's mileage as requested in the site posting instructions, but the thing is 22 years old so any number of things could be wrong with it. It would be helpful to know the details of what has been done so far.
