Hdi cutting out/batt light flashing

[Poodle]

There's no stop solenoid on these, if it's died while driving i imagine the alternator hasn't been charging for a while and the ecu has shut things down. You mentioned the belt slipping, has it been squealing then? If not, I'd check out your main earths and positive lead connections and if they're fine get your alternator tested. It should put out about 13.5-14V at idle, can check it with a multimeter.
