Help! Temp guage pegging and truck "reducing power"

ok guys. I need some help. While pulling my 5000lb trailer, my truck will peg the temp guage on full hot and cut back the power. I can restart it a couple of times and it goes back to the normal position. I dont think it really running hot. I have noticed it happening more on uphill pulls. It happens on all three settings of my SCT tuner. It does not seem to be triggered by high egts either.

Any ideas? I love the motor, but this is driving me nuts!

If you're running hot from pulling a 5000lbs. trailer, you have a major problem. Also try shutting of the programmer and see what happens.

thanks

I don't think it is really running hot.

Is it ok to run it on the stock setting without a dfp?

Just an update. I replaced all the temp sensors, and the last, and easiest one on top of the motor was the problem. It was all black and sooty. The truck runs much better and has not had the problem again.

I could start it right back up, even while it was rolling in neutral. It would reset to normal immediately.
