Alan,   
        To me, the fact that the radio is "sputtering" on and off seems to 
be the telling point.  I'm assuming that you have a non-factory 
radio, so tell us, what wire did you tap off of for the switched 12V 
power to the radio?
        I don't know why an electrical problem would just happen on 
acceleration, unless there's a loose connection somewhere.  What 
happens if you change the RPMs by DECELERATING?
        What happens if you rev the engine with the transmission in neutral?
