I have a 92 88 that will start fine an run for about 15 min then dies. Wont restart. But then if it sets 15 to20 minutes it will start back up an do the same thing. Can you trouble shoot this for me

When the problem occurs, if it cranks good but won't start, have a helper crank it while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one.

To check for spark, pull a spark plug wire off plug, use a known good plug or spark tester in plug boot. Ground metal part of plug/tester to metal part of engine, engine cranking, watch for spark. Also, you should be able to check for mil codes, if there are any?
