Problem began by exhibiting the "crank but no start" behavior. Was told that perhaps the computer chip in the key was not transmitting correct data and to get a new key. Next it stalled at low speed (approaching a stop sign), and would not restart until approximately and hour had passed. Then stalled again at low speed in a parking lot, re-started 15 minutes later, and then stalled for the last time in the same parking lot. Called for a tow and left it. The car started fine the following morning so was able to get it onto the tow truck and get it to the shop. The crank shaft position sensor was replaced, and so far no more problems.

Car starts up every morning however when I shut it down to go into store, gym, restaurants etc. many times (but not every) it won't start again unless I wait 20 min. or more (sometimes an hour).
Any ideas why?
Takes alot of fun out of driving the vehicle not sure if I go out to dinner if it will be a hassle to get it going again.

Engine would die, then restart after cooling for 15 minutes. Sensor was replaced for $285 and all is well.

The engine turns over once or twice but will not start, repete the process a couple of times and the engine starts.

Car would not start, ignition turned over but would not start. Started occurring occasionally with increased frequency until finally would not start at all. Mechanic shop replaced crankshaft sensor and all is fine now.
