Im starting to second guess my purchase now. It did not fix it this is what happens. Today while going making a hard left hand turn the truck just shut off. Then turn the key back on cranks fine runs fine until 3k rpm then its horrible. Last time it cut off while making a hard right turn and then only after that is when it runs like like crap and wont go past 3k rpm. Oh and hear is the catch only does it in DRIVE not IN Nuetral. What can this be the? IM lost and I think the dealer is to. The truck is still under factory warranty. Any ideas on what this could be? Thanks<!-- / message --><!-- edit note -->

 

Possibly a bad fuel pump would be my first guess. If it's under warranty, I'd make the dealer keep it until it is fixed.
