Possible Fuel Pressure Problem. Fuel Pump Check valve or Fuel regulator Perforated Diaphragm.
Locate your Fuel Filter, usually under back, near tank, after turning IGN to on Position then off, pop off the fuel line at the Filter...at entry end of the Filter If It squirts out (Not Just Drips) then your CHECK VALVE in your PUMP is OK. Repeat process and check the exit end of filter, Dripping out means Blocked Filter. Squirt means is all OK. Check fuel pressure regulator at Engine, remove vacuum line from REG, with IGN on, does it leak? Fuel system should maintain some pressure even after turning off. I'd suggest putting a bottle of Total Fuel System Clean through your next fill up.
