Exclamation Engine shutdown.

Hello. Sounds like you might have diesel bug. This multi-type organism thrives on carbon fuels and lives at the interface of the diesel and condensation water in the tank. When it dies, it produces a stringy type bio-mass which gets sucked up the fuel delivery line and blocks primary filters. This usually occurs when you need it least !!
Are you running from a single tank?
Original fuel source is usually the main suspect, especially when fuel has ben stored for a long period of time. Often now, fuel producers cut mineral diesel with a percentage of Bio-Diesel. (from 7 to 11%)
Bio-Diesel is more hydroscopic than regular diesel so attracts the water out of the atmosphere the bug needs to survive on. Bio-Diesel also wrecks regular neoprene gaskets and pipes, with the resulting chaos.
The "shelf life " is less than 3 months !! before it begins to seriously degrade.You can even get the bug spores from a wet deck after a rain shower. It only needs a minute amount to cause havoc in your fuel system.
There are test kits to acertain whether or no you have a problem. A smell of sulphur or bad eggs from the diesel will also confirm the worse.
There is also available diesel tretmant compouds, but be sure to get the correct one as some of them are very expensive and ineffective.
I could go on and on about this subject as it is a bete-noir of mine.
Happy to clarify any points if required.
Good Luck with it, Regards, Peter.
