When the problem is ongoing, if it cranks good but won't start, have a helper crank it while you check for spark at the plugs, if you have spark, it's not the ignition coil, but, you need to go further, If no rpm signal, you would lose spark--fuel injector pulse and possibly the fuel pump won't run other than the initial prime. The rpm signal comes from crank sensor. I'm not saying replace crank sensor, but, you need to do some testing, see what you missing. If the engine is hot wear gloves.
Cold sensor on thermostat housing fixed our 1999 Ford Taurus after it got hot it wouldn't start back
