ONLY RUNS IN NUETRAL AND REVERSE

Transmission problem

Starts but dies when you put it in drive and runs rough in park. If you put it in neutral or reverse it runs just fine.

Tis would have to be looked at by a pro, there is something screwy with this and needs to be physically looked at to give a good diagnosis.
