93 civic coupe b16, pulled my car in the other night to do a cam seal and my key would not come out of the ignition, so i stalled it out and wiggled and forced the key out. Two days later went to the gym afterwards i started my car drove about fifteen feet the car sputtered and died waited five minutes started up and drove it home. Its been doing this now randomly for about a week off and on (today in the fast lane on the highway) could my ignition switch be causing this? Ive got new plugs/wires. Checked dizzy for moisture its dry all grounds were cleaned and reconnected. Im at a loss here and camt quite pinpoint what do to next. Any input would be greatly appreciated before i start throwing parts at it. Thanks for your time any details you need let me know

 

If looked around to try and get a ignition switch but partsource doesnt sell just the switch they sell the whole assembly with key and all for 413.00 bucks any help?
