My 91' dies after about 10 minutes of driving every day. It turns right back on no problem. The heat gauge is also a hair above cold, but before it dies it increases to about 1/4. Is this my thermostat sticking??

if your thermostat was stuck open, itd stay cool but not die. if it was stuck closed, youd see your temp rise and definitely notice the temp diff. is there any other factors that contribute to it dying?

so it starts, runs for 10 min (give or take a few) every time? Then you restart, runs for 10 min, die and repeats? Sounds to me like a possible fuel issue. Like your fuel pump is pressuring the lines before starting, then once its started its not staying on. Once the pressure gets low enough, it shuts off. Forcing a restart, and re-pressurizing the fuel lines...maybe?

If i do not allow my truck to warm up, it will die within 10 minutes of driving. After it dies once it wont do it again.
