[Shotimes] Help with engine stumble in 95 MTX

ok here goes, I just bought my 4th SHO, a White 95 MTX

Now my problem is in 1st gear when i hit say 4500 rpms the motor feels like
it loses power and i have a mack truck
being pulled from behind.. I also notice if i shift at 4 grand and punch it
in second i get the same no power feeling
I can here the secondaries open up but then it falls on her face..

I'm not getting a check engine light..
Where can I start.. I know the wires and plugs and gaskets were done less
then a year ago, So was the CPS and timimg belt..
