Civic VX won't restart after coasting with engine off...

So, I've got a 93 Civic VX. I just did a tune up, I've only had it for about 1000 miles of driving. I am also an auto shop teacher, so I have a pretty good knowledge of cars, engines, and diagnostics, but this one is stumping me so far....

Pretty simple... I try coasting with engine off on the downhills of my 75 mile (one way) commute to work. I compression start the engine to get it going. I've done this all the time with my old/other cars. I've done this with 90% success with the VX, but on multiple occasions it has just not wanted to restart. It has occurred on long coasts (down a moutnain pass) as well as a short one (an off ramp). Of the 3 times it has happened, twice it started after a few seconds of being stubborn. The other two times I had to pull over and continue trying to start it with no luck until all of the studden it worked.

The X factor here for me is lean burn mode... I don't know a ton about it, so I am wondering if it could be related. Otherwise, any ideas?
