So I have had my 1990 4.0, ax-15 on stands for about 3 months doing various upgrades, the only one under the hood being wj booster. To do that I removed the air box. I ran it yesterday and it ran fine, I then put the air box back in and went to start it this evening. It starts after normal renix cranking time, then revs up to 2500 (normal) then dies, no sputtering, just dies. After a few more tries I found if I kept the key in the "start" position it will keep running and rev up just fine. As soon I let the key go from "Start" to "Run" it dies, again no sputtering, just dies. I did search and found a lot of no starts, but nothing like this. Ran out of daylight so cannot do much diagnosis right now so I was hoping for an easy answer. Thanks
