hello
I have an 87 v6 ranger with 5 speed that has been sitting for several years
the truck only has 48000 miles on it
the gas tank has been cleaned out and both fuel pumps have been replaced
the injectors were pulled and cleaned
it will start up and run for about 5 minutes and then will shut off
it will not start after that until the next day and then does the same thing
it starts up and runs then shuts off and can't get it to start again
could it be some kind of circuit breaker tripping or maybe the ecm
if it is the ecm how do you test it
thanks for any help or suggestions

Whats missing when it shuts off, spark or fuel? The ignition modules are famous for working when cold but going open when hot.
