Question: 94 pontiac bonneville dies while driving after getting warm... whats the prob?

I have a 94 pontiac boneville. After the engine gets warm, it stops accelerating and quickly loses power and dies. The catalytic convertor, throttle positioning sensor, crank shaft sensor, and harmonic balancer have all been replaced. Also, a tuneup was done less than a month ago. The mechanic at the muffler shop for the catalytic convertor said he is sure the front transmission mount causes it to die. is there any truth to this?
