Well I had pretty much the same problem once in my bug eye. Mine actually stalled on the freeway then managed to start and stalled again in a round about causing a huge traffic jam. Got it towed to subaru melville got the brant replaced and it had been running fine ever since. But its was a $300 buks bill. If that the problem u r having atm, I would suggest u to rip it out and replace it with an Autowatch or something similar. Hope this helps
