It runs good for two miles then it slows down and shuts off, and I turn it off and starts back up then it goes for one hundred feet and shuts off again.

Hi,

First, let's scan the computer to determine if there is a sensor issue, such as a crank sensor. You don't need a scan tool for this vehicle. It has an OBD1 system and only requires a short jumper wire or even a paper clip to retrieve codes. Here is a link that shows how it's done:

Also, this could be an indication of a partially plugged fuel filter or a failing fuel pump. Here is a link that shows in general how to test fuel pressure:

Before you test pressure, see if there are codes stored. If there are, let me know what they are. If there aren't any, check the pressure.

Let me know what you find or if you have other questions.

Take care,

Joe
