94 Suburban Dying

I put about 13 gallons of gasoline in the truck today(down to almost a quarter of a tank). I drove about 7 or 8 miles and it died. It was a little difficult to start but started and ran fine.(never happened before like this) Drove a another mile or 2 stoped shut it off and came back within 5 minutes and it started and ran fine.
Drove about 10 miles shut it off for about 10 minutes and started and ran fine. Drove 3 miles and it lost power and died, sounded really rough. Took about 5 minutes to start and it ran fine. 4 or 5 miles later at highway speeds it lost power again and died. Would not start. Walked to gas station for some starting fluid and came back and it fired right up with the starting fluid. Drove home 20 miles without a problem. Starts and idles fine in the driveway. The fuel pump and filter were changed a year ago this month. Bad Fuel? Water? Any suggestions would be great.

Since fuel was the last thing changed you might start there. You could check for contamination (i.e water, junk, etc.). I've seen vehicles starve for fuel due to pick up screen or filter clogged and a warm pump can not over come the restriction. If you have a fuel pressure adapter and gauge you could run with it connected and see what happens as it warms. Not sure what the 94 TBI pressure should be. (approx 13 - 14psi?) If fuel and pressure is good then it seems it is electrical and coincidental that it failed in relation to the fuel.

Electronic parts often will start to fail when warm/hot. Check for spark when it fails next. If no spark, likely the module in the dist. You could check to see if a local auto parts store can do a stress test to check it. Most will simply check it as cold and never see the issue. Maybe a hair dryer or heat gun can heat it up to simulate in truck conditions.

Any engine codes recorded?
