When I drive/park the Low Oil Pressure & Cruise Lights turn on & car shuts off.

What is your question?

1) When I am driving the "Low Oil Pressure Light" comes on first, then the "Cruise Light" comes on and my car shuts off. I then restart my car and it will not turn off on me for the rest of the day. 2) When I am waiting at a Red Light the "Low Oil Pressure Light" comes on first, then the "Cruise Light" comes on and my car shuts off. I then restart my car and it will not turn off on me for the rest of the day. 3) When I am waiting in a drive-thru line (ex: Bank, McDonald's) and I put my car in park but my car is still on the "Low Oil Pressure Light" comes on first, then the "Cruise Light" comes on and my car shuts off. I then restart my car and it will not turn off on me for the rest of the day. I took my car to my mechanic and he and his team did not see receive any "Codes", to let them know what the problem was. What they did was replace a new "CAM SENSOR" and new "CRANK SENSOR" and they drove it around (Forward, Reverse, Left/Right Turns, Etc.) and it worked for a couple of days but on the third day, it went back to the same problem. My mechanic and his team then replaced the new "CAM SENSOR" and new "CRANK SENSOR" with my previous "CAM SENSOR" and "CRANK SENSOR" and they drove it around (Forward, Reverse, Left/Right Turns, Etc.) and it worked for a couple of days but on the third day, it went back to the same problem. My mechanic and his team were confused and could not figure out the problem and they did not even charge me because they could not find the "Solution" to this problem. They shared with me that I should take it to a Chrysler Dealer, since my car is a Chrysler Concorde, and they will have the accurate diagnostic tools to find the problem. With everything that I stated above, it would be greatly appreciated if you can share with me the accurate "Solution" to my problem and/or if you can give me any great advice of what I should do next? Your feedback pertaining to my problem will be much greatly appreciated. FYI: I would also like to share with you that I have been out of work for over 2 years and sometimes I would not drive my car for a very long duration and leave it parked in front of my home. Some of my neighbors shared with me that I should drive it around sometimes and not leave it parked for a very long duration. I am sharing this with you because I would like to know, if my problem with my car occurred because I have parked for a very long duration.
