Is there any way to check if one is going bad. Intermittently it will just die like there is no fire.

HPDI, OX66 or carbed? If yours is a fuel injected motor clean the cranking battery cables real good because the ECU has to have 12v for the electric fuel pump so the motor will run. I have never had a bad Yamy power pack. Can be the high pressure electric fuel pump. Other possibles are the emergency kill switch, manual fuel pump diaphragm

It's an ox66. It cuts off idling and on plane. Doesn't bog down like it's running out of fuel, it just dies

Had to change the high pressure fuel pump on a 200 OX66 that guy said he was running down the lake full throttle and it just cut off. Would not start again, towed him in and found no fuel pressure. Yours sounds more like you are loosing your 12v power to the fuel control or the fuel pump relay is going south.
