My 83 sp250 was running fine, then three hours later wont start. what are the possible causes

reset the cut off fuel line these switches some time goes them selves

SOURCE: 96 grand am won't start!

I just went thru a similar problem. When I changed my fuel filter the problem stopped. I can't say that it is the exact solution for your problem. But it is a cheap fix if it is. You can remove the old one and tell before you buy a new one. The filter is located in fron of the gas tank. It comes off easily. If its clogged then replace it. ( I recommend replacing it evey year anyways). There are a few other possible problems that it could be. I hope this helps

Try some injector cleaner in order to see if the lean condition improves. Lean conditions can sometimes be caused by o2 sensors or other sensors that are not within specifications.

Sounds more like the coil is causing your problems. It overheats and causes the misfire you experience. Coil cannot be repaired. Needs to be replaced. Once the bike has died, take the plug wire off, remove the sparkplug and reinsert the plug into the plug wire. Now let the plug rest on the head. Metal part should be touching the head. Try to start the bike again. The bike wont start of course but you should see a blue spark between the electrodes of the spark plug. If not, swop the plug with another one. If you still dont see a spark it is probably the coil. Other possibilities are the generator and/or condensor.
