I have a 1998 Dodge ram 1500 5.2. She's old but runs beautifully. But when I drive it a few miles or so and turn it off. It will not restart immediately. It has to sit for a while. It doesn't have any other problems and I can drive it for hours as long as I don't turn it off. Wondering if I may be having computer problems.

 

Welcome to DF! Moving this to 2nd Gen Ram section for ya.

Might be computer, might be a sensor. What's missing when it won't start? Fuel, or spark?

 

The video below might help with troubleshooting, note it's a 2002 2500 which is still 2nd gen.
