Water in the fuel, faulty fuel pump, or VST needs a good douching. Would check PSI and probably end up disassembling VST if there wasn't anything obvious at fault. Have you taken a fuel sample of what is going into the engine?

Post the results of a compression test.----Apparently they had internal corrosion issues in and around where the head and block meet.
