Exclamation Engine won't keep running for more than 2-3 minutes

I have a 91 Ranger 4 cyl. that refuses to keep running. Here's what it's doing:

I can start the engine on the first try, it will idle smooth and rev smooth with no issues. I can even drive it at this point. After about 2-3 minutes, the engine just shuts off. I turn the key off, then back on. The fuel pump engages just fine, but once it stops, I cannot get it started again. It cranks and cranks.

After it sits for about 15 minutes, I can go back out and it will start right up again and run perfectly until that 2-3 minute point and then it stops running again.

I took out the ignition control module over to my local parts store to have it tested. I had him run the test repeatedly for about 5 minutes to see if it would fail. It tested just fine.

Now i'm stuck.....could it be a computer issue?

Any insight would be great.
Thank you!

Like clinton said...I would be willing to put money on fuel filter. I had the EXACT same thing happen to me on my dads old oldsmobile. It will be clogged enough after the preasure is built up and closes the line. After that happens it pretty much closes it off until the clog can "settle". I hope that makes sense. good luck!

I didn't think of that. That's worth a shot. I'll try that tonight after work.

One thought....if it is the filter, wouldn't the engine slowly lose power or start missing because of the decreased fuel before it cuts off? Mine just shuts off like someone just turned off the ignition switch. Any thoughts?

Its been about a year since its been changed. Still should change and definately worth a shot. Thanks for your insight everybody. I'll post what happens when I get that done.

For the price of a filter and a few minutes, I'd go ahead and give it a check anyways. :]

if I have to replace things (like fuel filters), I ALWAYS try the cheapest ones first. If you happen to replace 10 things and it still didnt fix it, well when you DO fix it, at least you have 10 things you wont have to worry about for a while =)

when it is cranking and cranking spray starter fluid into the TB......also pull the vacuum line off the fpr and make sure there is no fuel in it
