bucking and stalling

[douginhull]

Checked and cleaned grounds and connections to no avail. After running smooth for several miles the engine lost power so i put it in N and coasted to the shoulder where it continued to idle but would not accelerate????? Again turned the key on and off again the engine would idle but not accelerate. after talking real dirty to her, for no apparent reason, while idling for a while, as if to flip me the bird she just took off again?!?!?!?! any guess would be appreciated.
Thanks
