Crank and run bout 15 minutes thn dies after cools it will restart

What engine, there are 2, 2.5L and 4.0, I have both here.(wranglers)
can be 50 things , but in pure physics far less.
1:lost 12vdc electrical power, you see lamps and things dim out....
2: loses engine compression badly hot, one or more cylinder (a $20 gage finds it)
3: bad spark, caused by not doing tuneups at 60k miles.
and timing, test. for spark at each plug and check timing after a tune up we do that. full 60k. not just spark plugs.
4: bad fueling. this can be a huge list of possibles.
a: bad sensors.
b: low fuel pressure, fuel starvation ($20 tool to test)
c: too high pressure , engine floods, spark tips, soaked in raw fuel.
d; bad injectors (clogged, leaking or dead) $20 tool to test.

there are tests. for each class of failure. 1 to 4.
do you want to guess, or test. its your choice .
buy tools or go broke guessing.
