have a look at your ad-hoc connection side, a lot of wireless drivers 
doesnt support it well, I got the same problems with an intel 3945 with 
iwl3945 driver, the ad-hoc mode is bad, i have a lot of difficulties to 
merge bssids.

I suggest you to test only the connection between your two computers, 
without sharing connection first ( try some file transfers, between the 
two computers, wait a few minutes, restart a file transfer... ). if the 
connection is rock stable, then you can suspect the connection sharing, 
but I guess you wont.

a lspci could be usefull to see your wireless chip brand.
