There can be a glitch in the electronic tach that will show this speed increase that was fairly common and is remedied by having the dash unit repaired.So first you need to have someone verify that the engine speed is actually increasing. If the engine is doing what you suspect and it still has the rotary Ambosh pump you will want to have it repaired right away as the govenor is going bad and you take the chance of having a runaway. I don't know if the inline pumps have a similar risk.
