Tim: Did you swap back to your old coil yet? If not, do so before further troubleshooting.

The wiring to the WUR, AAR, etc. runs heating elements in those components during start and warm up. After the engine is fully warm, the electrical parts of those components don't do anything. You can unplug them with no difference. Therefore, even if you have a problem with the wiring to those parts, it will not cause the engine to stall after the engine has warmed up.

Since you are blowing the FP fuse it does appear you have a short in the wiring to the WUR or other component, so you will need to find and fix that, or just disable the whole circuit for now. If you disable the circuit, you will need to keep your foot on the gas pedal for a minute or so until the engine warms up. But that will allow your to continue troubleshooting. FYI, I removed the components and pipes and hoses from my SC engine to get rid of that crap in the triangle of death, but my car has a hand throttle, so I just set that during start and warmup. Now I can actually see and get my hands back there!

Try the coil first, because it's the easiest thing to swap, and you already have the old coil. If you are still having problems, then you can rule out a bad coil. Then check the green wire and CDI and distributor.
