For the last couple of months, while driving, every once in a while the engine felt like it would skip. Today it just died. I put it in neutral and coasted off the side of the road. It would turn over but not fire. Looked under the hood; nothing obvious. Fuel pump hummed; good sign. After about 20 minutes I turned the key and it started right up. Drove about 2 miles and it cut off again. Let it cool about 10 minutes and drove the last 2 miles to the house. I'm thinking it may be the crank sensor and hoping it's not the computer. Anybody had this problem and a fix?

Reason: added vehicle info
I checked for codes even though I had no engine light. None. Wouldn't I get a engine light if the CPS or MAP sensors were bad?Will check fuel pressure tomorrow to see if it might be my fuel pump on the way out. Also read somewhere that there might be a bad ground at the computer. That and vacuum lines will be checked.
I checked the fuel pressure and it was at the top of the range. Cleaned and reconnected the computer connections, put a steel brush and lube to the grounding bolt and checked all the vacuum lines. Changed out the CPS. Test drive....so far so good. Only driven a few miles but will put a lot more on it tomorrow. Thanks for all the help and offers.
