If you have a security system, close all the doors and then lock the drivers door with the key, then unlock it. That should re-set the system. I've had the computer completely disconnected from mine several times (used it to check another vehicle) and I don't have security...it started and ran fine...only difference between the two is the security so I'd try that.

Could be a crank or cam sensor gone bad. I suggest you get a haynes or chilton manual and do the testing outlined in them to determine which it is. Neither item is very inexpensive and the crank sensor is a real pain to replace. There are other things that can do that so testing is important.
Crank sensor is the most common failure but asd relay, wiring problems, bad ground on a relay etc can do much the same thing.
Anything you find that you need further help with I'll be happy to answer if I can!
