I have recently bought an 89 en450. After about 300 miles im having an issue where the bike just shuts off as I'm riding. Most of the time it will start back up immediately. Only had one time that it took a few minutes to start back up. Has anyone else have this problem. Im scratching my head because the problem won't last long enough to find a problem.

Had that happen to me. it is one of two things....either dirty contacts in the connector to the IC module, or, (in my case, and I am thinking yours) The IC builds up heat, and shuts down, then after cooling (sometimes immediately, sometimes longer) it will start right back up. It will continue doing this until one day you will be riding, it will shut down.....but will not start back up, as the IC has completely died. My suggestion is to be looking for another IC to be prepared, and sorry to say they can be kinda pricey.

I would also check the side stand switch is working this also would cut the engine while riding if it's loose or got bad contacts in the switch.

Where could I find one of these IC modules? Do they come new? Thanks

I've also got a suspected IC stall that is still intermittent and only at cruising speed. Here's a modern replacement which could be great fun to reprogram although I'm sure I remember seeing a pic of a stock IC opened up on this board with chunky 80s components I'd happily reflow or replace. Anyone else opened one up?
