95 Dodge Caravan Suddenly died while driving

On my way to work the other morning my Caravan started running rough and briefly quit runining. It was as if it was starving for fuel or oxygen. I got it onto the shoulder and popped the hood but did not notice anything wrong, I.E. Belts, battery cinnection, leaks. After a minute or two I started it up and was able to make it to work. It did stutter a couple more times. When I fired it up after work it took several trys to get the motor to turn over, as if it wasn't getting any fuel? I should add I put a bottle of "Heat" in the tank because I was suspecting some bad fuel. I "topped off" the tank the day prior to this problem. After finnaly starting, I made it home with no problem. I have a 42 mile drive to work one way.
