Engine will crank but won't turn over

What is your question?

It will stall while driving and some times it won't start at all. I could wait 10 minutes and it would start right up. I have been getting a jump from other vehicles and it would start. It sounds like it wants to turn over but now won't start at all. Can you help?

What makes this problem better or worse?

It seems like it's the same at all times
