No power over thirty mph

Hi! Just had turbo replaced and engine filter box. Turbo blew white, blueish smoke before replacing. Box was broken when animal ran under car. Took to garage and had repaired by friend of a friend (body and fender shop). Anyhow, new turbo was replaced and used engine filter box. Went to pick up car, started up okay, no smoke, idled okay left idle for twenty five minutes while at garage. Left garage and started home started up a grade and car started to buck, loose power and shut off. Started up again and drove seventy five feet, same thing. So I drove car on berm of road for two miles and made it home. Still have good idle, sitting at home, but if try to drive up incline car bucks and will shut off. Put dry gas and fuel injector cleaner, but did not solve problem. Any suggestions? Thank you!
