I have a FG50AT2-8 that im trying to diag a running condition on. The unit will start and run then shuts off anywhere from 10sec to 30 sec after started. I am leaning towards a fuel issue or a sensor since when it dies it still has spark. If you try to restart right away it will not start but has spark. If you let it sit 30 sec to 1 min you hear solenoid or relay click then it will start and do the same thing. I am not sure how to decode the faults. it is flashing the ! (exclamation) 3 times and the check engine light is on.
