I was going up a small hill after going through a knee deep stream. After going through the water it took about 4-5 seconds of 4whl dr. operation and it just died, It'll crank (plenty of juice coming from the battery) dist.cap & rotor are dry, all plug wires connected, plenty of gas into to the injector bar. It's been three days and it still won't start.

It can be a problem with one of the injectors. What is odd it that the ECU has not set a code for a misfire. I would have the ECU scanned even if your check engine light is not on. With a misfire the ECU should have set a code on which cylinder is missing. I would suspect one of the injectors is malfunctioning.

The problem sounds intermittent, if you put volt meter on the battery while it is at that 19volt mark/reading(on the gauge cluster) you will be able to see if it is true. If your alternator is really charging over 16volts the lights should be getting brighter then usual and/or they are burning out. Find out ASAP, if the alternator has a defective voltage regulator, it needs to be replaced. Prolong use will damage components.

Sounds like the ignition coil is getting bad.

Had same problem with my 97 sport, after changing almost all of the ignition components, it turned out to be the TPS.
