How long has it sat before you can start it up just fine? How long after you turn it off do you try to start it and it does not start? Are there any sounds associated with the no start condition( engine turns over normally, wont start. Or, makes no noise at all. Or makes a clicking noise)? Answer these in a little more detail and we can help you more. Being way2old is why I need help from younger minds

It starts fine first thing but after driving even for a few miles it won't start again. It sounds like it is turning over normal. After trying to start it I will let it set for a couple hours and than it will start.

Well, first we need to determine what is missing. Fuel or spark. You need to install a fuel pressure gauge on the fuel rail when it will not start to see what the pressure is with key on, engine not running. Should be around 42 psi. You can also purchase an inexpensive spark tester at your local auto parts house to check to see if there is spark when it does not start. So when we get these results, we can steer you to your repair. You can go out and buy many dollars worth of parts and finally det lucky or do these simple tests and we can start it for you.

You might check the fuel pressure. My 1995 mustang did the same thing while it was under warranty. Dealer had to replace the fuel pump. You can confirm this by hooking up a fuel pressure gage to the system with key on and engine off pressure should 35-40 psi and it should stay up. Engine running pressure should be 30-45 psi and fairly steady.
