Re: Well, I think I found my engine problem
I was reading your other post and you mentioned the MSD....You may want to check the connectors that attach the wire from the MSD to the Solenoid and the one going to ground ...Mine ( although used when I bought it) had those combo crimp/ solder connectors but they were never soldered...SO they started pulling apart causing the jeep to stall while driving it and rejump itself if I left it in gear.
When the plastic insulator heated up it allowed the wire and connector to break contact , as it cooled it pulled them back together allowin it to start or rejump itself while moving.
Kinda freaked me out driving at 50 MPH and have the jeep stall out, then keep coasting to get off the road and it self starts.
AS far as your tach problem ...my shop tach works off the TFI coil connection, For setting the timing . I do not have a tach in the jeep.
