I'm having an odd problem with my '99 SE 2.5 engine. It will cut out and stagger as the revs get up. What is strange is that it appears to happen as the fuel tank gets lower. On a full tank, the engine runs great. As it gets down near half a tank, the engine will cut out above 4000 RPM or so. Anyone else run into this? I'm at 65K on miles, and the engine has run perfect up until now.
