[InfiLights]

Thank you all for suggestions. I will start working on it.
Fuel pump first, check all hoses, clean filter heads etc.

The fire suppression system seems to be fine, light is green, no flickering but what if ? Anybody know how to bypass it and test ?

Bottom line is that the fuel in the small filter goes to half way and it quits. I refill the filter and it runs for a while...but sucks air somehow.
