[Legucygt]

Hi there guys a 97 legacy gt automatic and it keeps dying on the freeway it'll go for a couple hundred feet and then just stall out my speedometer will quit working my ABS light will come on on the dash and then the check engine light will pop on and then everything will just die and it'll start up just fine but like I said it'll go another couple hundred feet and then same thing speedometer will freak out ABS light will come on dash lights will get them and check engine light will comeI know I made another form about the PO 500 code could this be what's causing my car to stall on the freeway and the speedometer to freak out and then quit working altogether and then my dash lights get down and then the ABS light comes on they dash and then the check engine light and then it dies could it be my transmission speed sensor?
