Lose RPM guage and engine has less power

While driving my 01 Ram Cummins diesel down the road my RPM gauge will intermittently drop to 0 and the truck will start to run a little rough and seem to have less power. All the other gauges will continue to work fine. While continuing to drive the RPM gauge will start to work again and the engine begins to run smooth again and the power seem to be back to normal. The engine light is on so I checked the codes and got PCU-1693 and ECU-341. Any ideas what might be wrong or going bad?

P1693Turbo Charge Control Circuit Malfunction. . . .Id be wondering if your cam sensor is having fits and also check your MAP sensor and clean it if necessary.
