Trouble shooting

["Paula J. Graffam" <pjgraffam@juno.com>]

Listers,

Running up through top speed has been fine until I hit 5th gear @ approx.
65 to 75 mph and I start experiencing moderate bucking and skipping.

No skipping in all the other gears even at 5k rpm.  About 3k rpm it
starts up on me.  All ignition components are in good order.  Could it be
a fuel pump telling me something?  Looking for help.

Al Graffam  74  CT.
