My car starts fine the majority of the time. Twice in a span of 2 weeks, when I stopped to get gas, I get in my car and start it up and it turns over, but does not start. And when I turn the key, you can feel the entire engine shake in the front. Like it's a hard start. I have never had this happen before. The 2nd time it happened I brought it to my garage and they could not find anything wrong with it.

BUT after about 6 tries, and I do let it sit for a bout a minute it eventually turns over, but barely. Then it runs ok. I got to my next destination and turned it off and started it again and it hesitated a bit but it started no problem.

My mechanic said it was probably a fluke the first time, but when it has happened twice, it's not a fluke. And everytime after the 2nd time it starts no problem, UNTIL it will happen again.

Anyone have any suggestions about this?? Thanks
