Sounds like fuel pump is weak or the filter is restricted. check the fuel pressure at the fuel rail 48PSI.OK Next check the fuel pressure regulator pull the vacuum line off make sure there no fuel dripping or in the regulator.

Can having a bad connection on my positive cable going to my battery cause those same problems
