Driving down the road my blazer just cut out no warning, now it is doing it more frequently, several times a day and today won't start at all. It is not the fuel filter because I'm have gas there.

Improving fuel economy is easy - just take it easy. It willmake your vehicle last longer, too. Here are some specific tips on how to savemoney on both fuel and repairs.
Keep your tires inflated at the correct pressure. Under-inflation causes tire wear and wastes fuel.
Do not carry unneeded weight in your vehicle. Excess weight puts a heavier load on the engine, causing greater fuel consumption.
Avoid lengthy warm-up idling. Once the engine is running smoothly, begin driving - but gently. Remember, however, that on cold winder days this may take a little longer.
Keep automatic transmission selector lever into "D" when engine breaking is not required. Driver with the selector lever in "4" will reduce the fuel economy. (This is referring to vehicles with Automatic drive)
Accelerate slowly and smoothly. Avoid jackrabbit starts. Get into the high gear as quickly as possible.
Avoid long engine idling. If your have a long wait and you are not in traffic, it is better to turn off the engine and start again later.
Avoid engine lugging or over-reversing. Use a gear position suitable for the road on which you are traveling.
Avoid continuous speeding up and slowing down. Stop-and-go driving wastes fuel.
Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper distance from other vehicle to avoid sudden breaking. This will also reduce wear on your breaks.
Avoid heaving traffic or traffic jams whenever possible.
Do not rest your foot on the clutch or break pedal. This causes premature wear, overheating and poor fuel economy.
Maintain a moderate speed on high ways. The faster you drive, the greater the fuel consumption. By reducing your speed, you will cut down on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting the curb and slow on rough roads. Improper alignment not only causes faster tire wear, but also puts an extra load on the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corrosion.
Keep your vehicle tuned-up and in top shape. A dirty air cleaner, carburetor out of adjustment, improper valve clearance, dirty plugs, dirty oil and grease, breaks not adjusted, etc. all lower engine performance and contribute to poor fuel economy. For longer life of all parts and lower operating costs, keep all maintenance work on schedule, and if you often drive under severe conditions, see that your vehicle receives more frequent maintenance.
You have the battery and the alternator and the alternator belt and if they are working fine there must be something that is draining the battery. You need an auto electrician to check what the drain is. In such cases,on various vehicles, the BCM, body control module, proves to have something to do with it. Get A GOOD AUTO ELECTRICIAN to check if there is a particular component
draining the battery
it could be just contaminated fuel. keep an eye on it and if it happens again. let me know. also keep notes(i.e. time of day, cold/hot, driving/starting, just fueled, raining). all these can play important roles while diagnosing.
Check the mass air flow sensor. Unplug it, then try to start the engine. If it starts and runs ok replace the sensor. Make sure the wiring is good to the sensor, The wires may break inside the covering near the connector ends.
sounds like a fuel filter problem, when the engine shuts down,the blockage settles, then when driving, the fuel pump draws the blockage back.......check fuel filters
I had a Mazda 626 with a similar problem, the car seemed to 'shut down' with no warning, even at highway speeds, as if I just turned the ignition key to 'Off'; After trying to fix it unsuccessfully by replacing several electrical parts, the problem was found to be a defective ignition switch, it was replaced and the problem went away.
I had the same thing happen in my 1985 Nissan Pickup. It would just cut off. It was the fuel pump regulator switch on my vehicle. About a $50 item from autozone.
