Sounds like what my old 94 grand prix did. I thought it was transmission related because of the slipping and crap the transmission kept doing. But the funny thing is I kept expecting it to croak, so instead 3-4 months down the road my number 1 piston rod broke. So I suppose it could be engine related too. I never took the time to figure it out as it was a POS, 14 years old and had high mileage. I ditched it for $450 bucks to a friend and bought my 05 Grand AM GT.
