Reduced engine power, temperature jumping from normal to high, engine light flashing

I have a f150 2007. I was driving to work and alarms started going off warning came up reduced engine power the engine light was flashing and the engine started running rough and as long as I was running at low speed I could maintain speed as soon as I put it under a load I would lose power. I pulled over and shut off the engine check out the engine and found no over heating. Started the truck up and everything went back to normal. This has happened several times. Each time I try to put the engine insert a heavy load it does it.
What's wrong with my engine?

Get your codes checked first. Might help narrow it down.

Truck went into limp mode I would guess thats why no power. Why on the other hand it did could be a few things. When mine used to do that it was because the throttle body was sticking. I pulled it apart and sprayed it down with cleaner specifically for that. Make sure you have no power going to it because they do have a deicing strategy on and with the gear reduction inside it could take your fingers or cause serious harm. Clean it out well and do the maf sensor while your at it. I eventually came to the assumption that i was somehow getting dirt past the air filter and put a new intake on. Never a problem after.
