88' 4runner starts then stops holding no rpm

[brandon_2701]

After driving the truck all day or even just a little bit it will start up but then die out. Battery is good...i have 2 new ones i switch between. Starter is good, and the fuel tank is at 3/4 full......everything works just wont keep the engine running, also when the truck did run better i did the basic alternator test with the cutting power from the battery while running the engine trick. Any suggestions at all would be very appreciated thank you. Again its a 1988 white toyota 4runner thats an automatic with a 3.0 v6 that has 100,000 miles on it.


thanks,
Brandon
