Crank Position Sensor maybe? Located on the top of the transmission US
Driver's side.
You could try unplugging the connector, clean and tighten terminals and then
reinstall with some Di-Electric Silicone Grease.
If it works you could go for a little while maybe, but plan on purchasing a
new CPS soon.
It might also be a defective ign. switch, but you should be able to test
that easily with a voltmeter.
