I'll 2nd this question...when my '80 SC had a Permatune box installed, it experienced the same issues as the OP's SC...man, having the engine cut-off on the Golden Gate Bridge is a bummer!
If I recall, the tach would sometimes wildly bounce up/down just before the engine was cutting off or it would sometimes bounce and nothing further occurred...except my rapidly increasing heartbeat...it was stressful and after Permatune replaced the box and it failed again, the SC was fitted with original equipment and all was better.
Good luck with the diagnosis and repair!
