I was driving my 2006 powerstroke yesterday and all of a sudden I lost all my boost and check engine light came on:doh:. I had my scan tool so I pulled over and I got a p0299 underboost and I got a map sensor code. what could cause these to come on out of no where?

Check the hose that runs between the map sensor and intake manifold. Its located on the passenger side between the AC/Heater Core, and Hot CAC tube.
