I'm still beating my head against a wall with mine too. I can't get it to fail the same way enough to isolate the problem. I can get it to cut out wiggling the wires sometimes and other times by tapping on various components on the ECU. I was thinking of reinstalling my stock ECU and not starting but wiggling the wires to see if it's just wiring, but I don't know if the wire changes would somehow allow the stock ECU to fry a sensor.
