shuts of at 6000 rpms, has no rev limiter, starts right back up, runs great at low rpms, any ideas??

Several things come to mind..

1. Fuel line from tank is seperating because of eth. fuels..
2. Loose ground
3. Fuel pump ( small one on side ) cannot keep VST tank full running outta gas
4. Loosing fuel pressure
5. 8 pin plug coming from key switch harness is dirty
6. Battery suspect
7. Weak high side of stator

Fuel pump driver circuit in the ECU.. Try hardwiring the fuel pump and see if it still does it..

how does one go about testing the high side of the stator?

Here is what I had: Start up and run great. Sudden shut -off. Immediate restart with key. Idle fine. Back on plane and another shut down. Repeat.

I had the computer rebuilt twice. Then, the mechanic put some guages on the fuel pump (backed-in at the ramp and under load), did some inspecting and determined that the O-rings were in bad shape where the fuel line connected... allowing the pump to suck air after it emptied.....

So, he rebuilt the fuel pump and so far - I am back in business. Good luck.
