I have an 1989 4runner 22re 5speed 4wd. when I went out to start my truck it started and ran until it came up to temp. then it lost rpm.I pushed on the gas and it stalled out.Then I tryed to start it again and nothing (it would roll over). So I let it sit for an hour and went out to try again and it started ran died when it got up to temp. Any help would be mint.

 

Sounds like the classic symptoms of a bad signal generator. The signal generator is located in the distributor. When it goes bad, it'll show proper ohms when cold. However, as the engine warms up, the ohms go through the roof and the engine quits.

The signal generator can be ohmed out by unplugging it (it's the wire with a green plug coming out of the distributor and the other end of the plug goes to the igniter) and ohming it out. It should register between 140-180 ohms. Ohm it out with a cold AND hot motor.
