That is a typical problem with older vehicles especially with the bad grade gasoline we are using. I worked for Ford for years and I can just about bet that your converter is clogged up on the exhaust. When you loose power put your hand near the tailpipe (while the engine is at idle) and see if it is really hot when it comes out. BE CAREFUL !!! I have seen burns from this. What happens is when your vehicle is cold the converter has a honeycombe inside it and when it heats up the honeycombe that is already saturated expands and seals itself off. This is why you have no power. The engine has no place to release the exhaust. If ran to long like this it will probably cause you engine damage. Hope this helped, Good luck

You could try using petrol rather than gas to start it.
Also run it off petrol rather than gas.

Going down the road acts like running out of gas ,dies will not turn over again battery has full charge and clean,good connection but stell will not turnover till it has sat for a couple of days.then it...


Thanks for choosing FixYa and welcome. You may have a bad connection to the battery. Make sure all wires are tight and secure, also make sure the ends and post are cleaned. Your alternator may be going bad. If you can get it to start, start it and take the hot side battery terminal off, the red one. If it dies instantly, your alternator is going bad. If not, the alternator is good. Your starter may be going dead. Find it. One of the hot side battery wires goes to it. Follow the wire. Hit it a few times. See if the car will start. If the inside has power, the battery is fine. Check your igniton fuse also. It is probably your starter or starter solenoid.

Engine dies when running. Intermittently dies while running no sputtering or other warning, all of a sudden the engine is off. Mostly happens at lower rpm's. Starts right back up after putting it in park.


first thing to replace and cheapest would be the fuel filter ,if that doesn't fix the problem , it may be the fuel pump . GM fuel pumps are in the gas tank, and they have a built in thermo fuse . when fuel pumps get old 60000 miles or so..the motor in fuel pump starts running to hot and the thermo fuse kills the power till it cools down then it will run till it gets hot again note the cool down time keeps getting longer and longer
