My car wont start

I recently drove my car for about 4 hours straight. I have never had a problem with it before. But when I got home I was inside for about 15 minutes, I came back out and my car would just crank start for a second and die. I left it till the morning and it started perfectly. I let it run for about 10 minutes turned it off and went inside. I came back out about 30 minutes later and it started again, I then went to pick my kid up at school which was a 5 minute drive the car was off for about 15 minutes i got back in and this time it didnt start it cranked over and thats all it would do HELP!

What model of Dodge and what year?

oops sorry. It is a 1990 Dodge Shadow S

sounds like a distributor problem, try replacing distributor cap and the distributor itself..
