so many issues

ok so im new here n new to diesels so if i say something stupid forgive me, So i just got an 11 f550 w the 6.7 and was out plowing n out of no where i lose all the heat in the cab then a bit later it over heats and starts losing coolant,So i stop n when the truck is parked and running it cools back down it only heats up when im driving it.Not sure if this ihas anything to do w it but once in a while it would just seem to lose power when i hit the pedal,we did a thermostat yesterday while the snow piled up n didnt change a thing except the fact that now 1 truck was doing over a 100 driveways 5 rds n 2 parking lots wich i dont want to do again so any help is much appreciated
EDIT...another thing is like when it says that its overheating it doest seem hot at all ,normally you would know the thing was hot but i took the caps right off
