4low keeps popping out

I have an 88 GW and am having an issue when I go from 4hi to 4 lo. After I engage the 4wd I put it in neutral and pull up on the floor selector for 4lo. It goes in OK, but after I put it back in drive and move forward a few feet it pops out of 4 low. I have no idea what to loom for or do with this since I'm still new to fwd. Any info would be helpful. Thanks

A couple things come to mind. It could simply be that the shift linkage is out of adjustment.
Or, it could be that your engine, trans, and T-case mounts are all worn enough to allow the drive train to torque(twist) enough to pull the T-case out of lo when throttle is applied.

There is a chance that it's something internal that's worn, like a shift fork, or gear or chain. However, unless it's making noise, the linkage or mounts are more likely to be the cause.

To adjust the linkage,
1: Disconnect it at the T-case, and manually put the T-case into lo.
2: Move shift lever into lo position.
3: make adjustments to linkage so that it will reconnect with arm on T-case, and reconnect.

If adjusting the linkage doesn't fit it, take a look at all the mounts.
