I was driving 55 mph on the highway and it just started losing power.I eventually came to a stop and I barely keep it running. I shut it off and opened hood . The Exhaust manifold was bright cherry red. I let it set overnight and it still won't start this morning .Any ideas?

A blinking light usually means exhaust system probably catalic converter. You most likely have a small blockage in it which means exhaust can't get out correctly. Have vehicle scanned at autozone or similar.
Avoid idling. While idling, your car gets exactly 0 miles per gallon while starting the car uses the same amount as idling for 6 seconds. Park your car and go into the restaurant rather than idling in the drive-through. Idling with the air conditioning on also uses extra fuel. Also, avoid going so fast that you have to brake for someone. Whenever you brake, you waste the gas it took to get going that fast.
Drive at a consistent speed. Avoid quick acceleration and hard braking. Cruise control will keep you at a constant speed, even when going up and down hills.
Avoid stops. If approaching a red light, see if you can slow down enough to avoid having to actually stop (because you reach the light after it is green). Speeding up from 5 or 10 miles per hour will be easier on the gas than starting from full stop.
Anticipate the stop signs and lights. Look far ahead; get to know your usual routes. You can let up on the gas earlier. Coasting to a stop will save the gasoline you would otherwise use maintaining your speed longer. If it just gets you to the end of a line of cars at a red light or a stop sign a few seconds later, it won't add any time to your trip. Ditto for coasting to lose speed before a highway off-ramp: if it means you catch up with that truck halfway around the curve instead of at the beginning, you haven't lost any time. In many cities, if you know the streets well, you can time the lights and maintain the appropriate speed to hit all green lights. Usually this is about 35 to 40 MPH.
Slow down. Air resistance goes up as the square of velocity. The power consumed to overcome that air resistance goes up as the cube of the velocity. Rolling resistance is the dominant force below about 40 mph. Above that, every mph costs you mileage. Go as slow as traffic and your schedule will allow. Drive under 60-65 since air grows exponentially denser, in the aerodynamic sense, the faster we drive. To be precise, the most efficient speed is your car's minimum speed in it's highest gear, since this provides the best "speed per RPM" ratio. This is usually about 45 to 55 miles per hour.
Use A/C only on the highway. At lower speeds, open the windows. This increased the drag and reduces fuel efficiency, but not as much as the AC at low speeds (35-40 mph). The air con - when used a lot - is known to use up about 8% of the fuel you put into your car.
You got it, definetely is the symptoms of a bad catalytic converter including the smell.
Fortunately there is only one
Unfortunately they are very costly
You may also notice that if the vehicle is idling for awhile and you look underneath the exhaust may be glowing red in some areas, extremely hot
Hope this helps
First thing to check is the transmission fluid. Check it with the trans hot, the engine running, and the trans in "park". Smell the fluid while you check it and look at the color. It should be bright red with no burnt smell. This is usually the cause of most "slipping" problems and loss of Over Drive.
The only thing that comes to mind is the catalytic convertor in the exhaust system.It can become restricted,reducing flow in the exhaust system,which also reduces engine power.These convertors run at fairly hot temperatures,and the extreme heat and conditions aggravated,or overloaded it.It's not very expensive to have it checked at a reputable muffler shop.I have seen extreme instances where this caused parts of the exhaust system to turn red,glowing hot.
