Loss of power while towing

Newbie here, have had my 6.0l for about 8 months. (108k on the miles) I haul a 32ft bunkhouse (9500lbs loaded) TT 7-10 times a year (mostly short trips) 1-3hr drives.

Last trip it towed out with no problems at all (ate the road and hills up) on the way home (1.25hr run) the wrench light came on and I lost power. It would shift smoothly between gears, start from a light fine, and on a straight line would get up to 60/65 seemingly fine.

When hitting a hill it would lose speed and power, I could have it floored and nothing! No rev, no speed, would even downshift but not give me any power. Took it to a ford mechanic and they couldn't find any stored codes. Suggested iI replace EGR, Oil cooler and clean turbo (all to the tune of $3500.00)

After parking overnight and restarting, no wrench light and seems to running great... Towed the camper on a short run (16 minutes) just to get it back to the storage facility. Seemed fine.

Any thoughts?

read the stickies here in the forum and you will find all you need...

The wrench light is telling you the truck is in "limp home" mode where the power is reduced due to over temp on the oil or coolant. Do you have separate gauges for EOT, ECT? You need them. The gauges on the dash are actually more of an idiot light. They stay in one spot until you are on the verge of shelling the engine and then they move into the red when it is too late.

The reason for going over temp on EOT or ECT are many and you won't know the root cause until you install some gauges (or an Edge insght or other smartphone based app) to monitor the temperature. Could be radiator, water pump, degas cap, dirty system, oil cooler, head gaskets, etc...
