Yesterday driving back from work past 4-5k my car began to hesitate and the speedometer erratically fluctuated then stopped reading once my rpm dropped below 4-5 this it slowly ramped back in to normal .. I checked all my earths cleaned them up and drove it with out an issue it happened again this morning has anyone come across this before I have very little time to find the fault.. Cheers

A link to a video of whats going on if anyone could shed some light on the situation ...

This sounds like a wiring problem, or a problem with the main relay. Check all connections for corrosion.
