[T2] Powerless 1800 cc

[david raistrick]

definitely sounds like fuel starvation - in addition to the things Al
mentioned, when it happens, pop the gas cap and see if there's suction
on it.   you may have a tank venting issue that's not allowing air
into the tank (to replace the fuel that's removed).
