My 1995 ram 5.9 V8 has been having an intermittent problem. When I am out driving around town and shut the truck off 3 or 4 times in a short period of time it won't start. It tries to start but doesn't idle properly and has about 200 rpms and eventually dies. If I let the truck sit for about 15 to 20 minutes it starts up fine and I can drive it with no problems.
