From what you haave posted it appears that more information about your set-up would help. Option 2 appears to be the only one that offers reverse, but is your set-up in line with the rest of the Option 2 requirements? Are you running Lipo's, how many? ect?.
While the ESC sounds like a racing, or at least a high speed unit, maybe posting in a fast electrics forum with bring you more responses.
Last comment, when an ESC becomes unreliable, it is generally time to fix it, or replace it. Further reliance upon it may well spell trouble.
