Suddenly No Spark-need HELP please!!!

[rseeley]

I drove the truck about 15 miles this morning and it ran fine. I went to leave where I was, it started for a minute or two then just abruptly quit. I checked for spark, but there is nothing. It turns over fine, just doesn't fire.
I am thinking coil pack or ignition module. Any input would be greatly appreciated as I don't have much experience with electronics.
Thanks,

You are in the right aera to start, but the first item I'd suspect would be the crank sensor.

Mike-
Thanks for the advice. I'm assuming that the crank sensor and the crankshaft sensor (as refered to in the Haynes manual) are the same? If so, is this accessible from under the truck? It's hard to tell from the manual, but they make it seem like it's out in the open and only a matter of removing 2 screws. Any idea of cost or availability from a local parts store?
Thanks,
Rob
