Your cut-off problem could be due to the ignition switch. Take a look (http://shbox.com/ignsw/ign_switch_repl.html).

Let's move this to "V6 Tech", where it belongs.

My 97 Formula has the same problem.

I have also found that if I hold the revs constant, say at 2K RPM, the engine will fade to 1500 RPM then surge back to full power.

This happens at a steady interval of about 4 seconds

Check the fuel regulator vaccum fitting on the passenger side rear of the intake manifold. My 00 V6 was hard starting at times and I could smell gas. After some digging around I checked that fitting and the rubber connecting the line to the intake was cracked. I replaced it and that one dried up and cracked as well about 2 months later. I replaced it again with another fitting and it has been fine since. There was no visible gas leak on the ground, but looking at the rear of the motor on the passenger side you could see it was damp like it had been leaking. I'm lucky the thing never caught fire leaking gas down the motor like that.
