93 Wrangler 4.0 Died on the highway help is appreciated

[cyberg]

Wouldn't start this morning, finally had to push the gas pedal down, then it started.
Going down the highway 65MPH and the engine just died. Turns over but will not start. Made one slight *pop* as it was dying, like a super wussy backfire.

I really have to get this going, its my only vehicle and I have no way of getting to work, any help is really appreciated.

How can I check the coil? Seems like its not fireing, how can I check spark?

Thanks for the help, CYberg!
