Looking at your tach. It looks like the RPM drastically drops off, almost like an electrical problem? Then comes back up. Not sure if that's what you are referring to.
Whoa! Let's not bring up those bad juju gremlins in here....:poke: lol
Could it be a sharp electrical draw that causes the engine to bog before getting power. To me it feels like it runs out of gas before catching itself and starting to go again...
