Experince with B&M 50442 - B&M Tork Master Converter

Hello! I have another thread going on in the small block tech about sudden loss of get up and go power. Here it is if you are interested: http://www.forabodiesonly.com/mopar/showthread.php?t=277904

My car is all of a sudden sluggish of the line and I cant for my life understand whats wrong all of a sudden. It runs great, no bogs, everything is tuned and it ran great just a week ago. It is like my converter no longer stall the 3000 it should. I dont know if it is because my engine lost torque or if my not even a year old converter has gone bad. The trans was gone through by a shop last summer and the converter I put in at the same time. A B&M Tork Master 3000 stall. What I'm asking here is, have anybody had a converter gone bad that fast, especially a B&M. I know it's a cheap one, but I dont have the most powerfull enginge either. The trans shifts great, but the converter don't flash or slip as it did before when taking of. Im suspecting it is not the engine because like I said, it runs great but is sluggish of the line, no bog though. Here's the combo. And again, it ran great last week, just as it always had before with this set up.
