95 Altima stalls in drive

Hoping someone can help, my Altima has developed a problem, in neutral or
park it runs and revs just fine, but when you put it in drive and hit the
gas it chugs and hesitates and then eventually stalls out. There is no
check engine light, only code is for a knock sensor. Sometimes it will
run fine for a while.

I have the same problem did you figure it out, if anyone knows what it
could be.
