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?
