F150 with 5.0ltr, starts then stops 20 seconds later?

I got a 88 ford f150, it ran fine with no signs of any problems, then one day it would start up like normal, run for 20 seconds or so...then it would stall...thats all it will do now...if i start it again after it stops it runs normally for 20 seconds then dies...anyone know what causes this? Internet sites point to a IAC, or a part on the distributor, but I wonder if anyone else might have seen this before and know?

    Its either your IAC of TPS the only way to tell for sure is buy hooking it up to a computer, or trial and error. If the computer says theres no problems you mught have water in your gas.
