Bought this 99 1500 5.2 4x4 a week ago. Last night, and again this evening, while driving at 70mph with the cruise set, had a total loss of power on a relatively flat road. Exited the highway, had no real issue accelerating again, to 50mph speed limit, that is. Help please!

Gonna try driving later without cruise on and see if there's a difference.

 

I have had issues from not using it much, but the problem seemed to go away.

 

Scan it and see if any codes were set, but I wouldn't rule out a fuel related issue if it had been sitting for a while before you got it.
