Have a 1988 chevy 1500 with a 5.7 350 in it. Driving down highway at 70mph. Started losing power more and more the farther I went. (This is all in 30 miles) I eventually had it to the floor to keep moving and than smoke started coming out the back end of the truck. Oil pressure dropped extremely and as soon as I pulled up to a stop light it shut down immediately. After 30 minutes. It started right up as long as I kept it above an idle. No knocks or squeals of any kind and had good oil pressure again. Drove it 3 miles and everything happeded again. 30 minutes later I repeated the process and everything happened again. What could that be? Anyone?
