not if it's a low fuel issue.

what was the fuel pressure spec/reading??

does it actually run when the return line is pinched off??

if it still stumbles, then what i suggest is check the fuel pressure and see if it drops off when the stumbling occurs. if not, then you may have a different issue.

then i would check the crank and throttle position sensors.
