What I mean is, watch it when it dies. If the tach drops right to zero quick, you are losing your tach trigger. If it falls "with" engine RPM, then something else. Might give you a clue where to look
Ooh yea I see. Yea it dies die with rpm. I even made a data log of it and nothing stuck out. Rpm fuel px and batt volts all increase when it starts and it all falls when it dies.
Only thing that looked different is the afr from the O2 sensor never comes on.
