2000 xterra 3.3 runs fine shut it off after warm and no spark.

What is your question?

Xterra 3.3 Starts fine when cooled off but after warmed up real good it has no spark after i shut it off and try to restart .If I wait 1 to 2 hrs it starts like never had a problem . Will run fine till I shut it off and strong smell of gas if I keep cranking it. So plenty of gas . Just no spark went out to eat ran good came out about 30 min later no start. Cranked real good . Strong gas after I kept trying. Waited about 30 more minutes started and I drove home. Shut it off and would do the same.back to no spark.

What makes this problem better or worse?

Only when warmed up to operating temp
