Update.....Just got the my Tahoe home after sitting all night in a hospital parking lot. The rollback driver said that when he got in it, he started it up and it started fine. He said he drove it right up onto the roll back and had no issues at all. When he got here, he got in it again, started it up and backed it right off the roll back, It did not die at all,. My husband got in it, started it, and turned it around in our driveway so that he would be able to get underneath it if need be. All seems to be running fine. What is the deal here??? What gives????? Suggestions????
Mrs. Cusser was in this Frontier, returning from riding her horse. The truck just stalled half-way back on the road while driving at 45 mph, in the left lane on a very busy road; so I told her to call AAA and have it towed to the house like 5 miles away. I got to that location before AAA, I tried to start it, engine just cranked/spun but would not start, as it did when it stalled for her. Once towed home, I tried to start it, engine just spun but would not start, as it did on the road. I began by trying to isolate whether issue was spark-related or fuel-related, what I'd typically do. So I sprayed in some aerosol starting fluid, then it started up, rough for first 30 seconds (like trying to stall if I took my foot off the gas pedal), then after that it appeared normal except that the "Service Engine Soon/Check Engine" light was on. And the truck started right up after that, so I drove it 1.5 miles and had the check engine code read at 2 places, both read it as P1320 which is generally a distributor or coil issue (this has a distributor, not individual coils). I cleared the check engine code by disconnecting the battery for 1/2 hour/connecting the two removed cables together, and the check engine light has not come back on. Now it's 2021 and this has NOT happened again. Even Mrs. Cusser is no longer fearful of driving it.
Unfortunately, I did NOT check for spark before I sprayed in the starting fluid and it started up, so I don't know for sure yet if it would've shown absence of spark then.
I'm sure Mrs. Cusser has no idea if the check engine light actually came on just before it stalled out.

Relays are todays erratic failure. They can lose contact internally erratically. I'd change out the main ones like ECU and fuel pump. They are cheap enough and no way to check for burnt contacts inside without breaking them apart.
Relay issues usually do not set any codes either.
