truck issues

Just took my 2010 raptor to the dealer I was driving and started losing power I would have to smash the gas to gain a little speed. Started shaking when idling to. The dealer said there's no engine compression so we need to dig around more he said so far my warranty covers it since it's the engine. So just waiting for a call for the next few days. Just hit 98,000 miles....... any ideas think I'll get a new engine?

Probably get either new heads or a new short block, doubt they would rebuild it, lol.
You must have an extended warranty to cover this many years?
