1994 jeep cherokee Starts runs for a minute and then dies

Check under the hood on the driver's side near the firewall, screwed to the top of the inside of the fender. There is a transistor (I think that's what it's called)... point is, there are two wires attached to it. If either is loose, corroded, or disconnected, it will do exactly that. It's for the fuel pump. When you start the engine, it uses a different circuit route than when it's just running- routing around that transistor. When the engine switches back to normal, it runs through that broken line, and uses what little gas is left in the line, and dies. This may not be your issue, but if it is, checking will avoid a lot of headache.
