I can drive my 1999 dodge intrepid for a while and cant start it

I had that same problem i replaced the entire Distributor and ran fine after that

Many vehicles turn on the electric cooling fan if the temperature is high under the hood which prevents hard starting of a hot engine.
If yours never has had the fan run for a minute or two, then it isn't supposed to but if it did it once but now doesn't, the thermal switch that should turn it on has failed.
Try holding the gas pedal to the floor before turning the key; if it starts, then there was too much gasoline in the cylinders causing wet plugs which don't want to fire.
