Truck Gauges and Air Conditioning Intermittent?

I have a Ford F250 Power stroke. While driving all my dash gauges and air stops working. They just flat line and then a couple minutes later all is good. What could be causing this? Also this only happens once in a while. Sometimes not for weeks.

You have some sort of electrical short that is causing this problem.
Most likely the reason it only happens once in a while is the bad wire touches another wire or some part of the truck.
You should also check your fuses.
An electrical short is probably one of the more difficult problems to solve as you may have to check the complete electrical harness to find the problem and as you can see it is intertwined and involves all of your gauges.

This could be dangerous so please get it checked out as soon as possible.

You might try going to a local auto parts store - AutoZone, Advance, Carquest, Pep Boys, most any of these have system checking machines and they may be able to help you. Not all of them will have the machines but keep trying until you find one as a dealer will charge just to check it out.

It's possible you could find the problem if their machine can help you. Otherwise you will have to take it someone (dealer) who has an experienced person working on electrical systems.
Sorry, but it will probably be an expensive repair.
However, it will only get worse if not fixed and it may start affecting your lighting system or anything else that works off the electrical system.
Try the auto parts store route first.

This is an electronic short in the car. My daughter had the same issue in her car, but it is the same as your truck. All of a sudden all the gages would shut off and then after time they would come back on. If this is not taken care of soon the engine will be effected and all of a sudden you can loose power to the engine and the car will stop running.

You will need to pull over and wait around 40 minutes or so before it cools off and you can go again. In her car they replaced a few electronic switches but they were unable to find the problem and it persisted because she waited too long to have it looked at. That is what they told her.

The computer system in your truck, has a malfunction or loose terminals. May need adjusting or repair.
