Erratic temp gauge and p1092

[Dante2795]

After about 10 minutes of cruising temp gauge shoots all the way up then truck says “ENGINE OVERHEATED LET IDLE” but will then go straight back to normal. Then Rail pressure starts going all over the place from 0psi up to 27 then back to desired. After it does that for about 5 minutes it’ll finally limp and say p1092. Truck sounds horrible and has no power with both code cleared and not cleared. Then p0193 will come up. And it’ll keep going back and fourth. Then finally p0652 will show. Any ideas before I start throwing money at sensors. Meanwhile all this is happening the temp gauge is going all over the place.
