Car won't start. Could miss Carlisle! Please help.

My 68 Dart would not start this morning. I put a 72 340 in it last year. It always starts and runs fine. The last ride was on Sunday, no problems. Normally, I turn the key, it starts, I let go of the key and give it a little gas and it runs at idle fine. This morning, I turn the key, it starts, I let go of the key give it gas and it dies. I tried about ten times. It did the same thing every time. I plan on driving it to Carlisle Saturday morning. Any advice will be greatly appreciated. Thanks.
