Default spark then no spark, spark then no spark

one minute my 4.3L v6 (from a 1999 silverado currently resting in my cj-7) starts fine and will idle as long as I have gas. Then 10 minute later I try to start and I get no spark. 10 minutes later I am getting spark again and starts and runs like a champ. I replaced the ignition coil- no change. Seems to be random on if I get spark or not. What else could it be besides ignition coil? I am running factory computer and harness. Thanks for the help.
