97 stroker random stalling

Can't say why this happens but randomly the truck will cut out when its first started for the day. I'll start her up and go in the house and come out and its just sitting there, lights and heater going but not running. I've caught it before but can't seem to nail it down, seems like its not getting fuel. Also noticed that at times the truck will surge and I noticed the volt meter surging. Not sure whats up here. I've replaced the cables, batteries and alternator to no avail. The fuel filter is new and clean. Any help would be apprecieated as its my only truck and I need it to be a working class hero for my kids. Thanks all.

Try unplugging the ICP located on the drivers side head towards the front. Do you routine, start it up, let it warm up, see if it dies then.

The ICP is the Injection Contol Pressure sensor. It is on the front end of the driver's side head, pointing inward at a 45 degree angle. It has a 3-wire connector on it (and there should be no oil in the connector when you unplug it). If you have an auto tranny and try to drive it with it unplugged it will shift extremely hard. But for a test as mentioned above, you should be OK. Cheers!

CPS CPS CPS!!

Are you familiar with the infamous Crank Position Sensor? That little 40$ pos can be responsible for every symptom you can imagine.

Seriously dude, try one before you do ANYTHING else. If it's not it, chuck it in your glove box and hang onto it cause a) you will need it eventually and b) you should be packing a spare anyway.

When this happens, does it start up again easily, or is it troublesome re-starting?

The truck does restart no problem and like I said its super random, usually just when its cold, first start situations. Should I have this beast hooked up to a computer or something? I have no check engine lights on or anything. Where is the cps? Easy to change?

Yep try a CPS. Super simple to change. 10mm wrench and flat screwdriver to pry it out. Unplug the wire, pull the one bolt, pop it out. Reverse the process to reinstall. Sort of looks like as asthma puffer plugged into your block, right down from the harmonic balancer on the front of your engine. Lay on your back, scoot under front. Can't miss it.
