Crank no start after hot soak - 2005 Jeep Grand Cherokee

Is the check engine light on? How long has it been since the engine was tuned up? A worn plug that is "hot soaked" can create a longer cranking time. Hot soaked means it may have some un-burned fuel in the cylinder since the first cold start. A weak or worn plug has a harder time getting this fuel burned out of the cylinder when more fuel is being added during a warm start.

Check for spark on a plug wire when it won't start. If no spark until it cools down, the ignition system is the problem. Could be the coil, the ignition control module (igniter), a crank sensor or pick-up coil, depending on your system, ...some of the most common things to check. If it just stalls, likely lost spark or gas to the engine cylinders. With a new pump, it probably lost spark.

When you say travelled 10 miles then would not start, do you mean it would not crank at all, or cranks but doesn't start? If no crank, could be faulty starter motor/solenoid getting heat soaked. If it cranks but won't fire up, more likely bad ignition module, coil, crank or cam sensor. They get hot and can fail just when hot.

Do you mean it won't crank over, or cranks but will not start? If the first, likely a heat soak issue to starter motor. If the latter, check for good spark, and check to see if engine is flooded. Flooded might mean bad/leaky fuel injectors or bad coolant temp sensor.

sounds like you may need a new ignition coil.

NO start, but cranks ok ! (guessing i am on that cranking bit...)
no engine size stated, so cant be ACCURATE.
wont start hot. ok cold
so when hot it fails, and when hot that is when we try to fix it or diagnose it.. not cold.
so got spark on all unstated engine cylinders?
all must work not just one
ever get a full tuneup this decade or even ever?
when it dont start, did you read the oper guide.
and do the wide open throttle , cranking, and see IF the engine unfloods? (this is feature on all EFI cars).

all cars do this ignored, all do.
service it? ever?

if spark is good, try test fuel.
if test fuel works for 3seconds, or starts and runs hot, say so now?
if test fuel fails, check spark tips for soaking in fuel or bone dry.
if soaking, , its flooded,
if flooding it is, we work flooding
ask.how, (can be many reasons. more tests... )
like that....

i offer only one guess, on all cars, all cars ignored!!
eva get a tuneup?

Sounds like a "HOT SOAK" problem.
Starter gets hot,it lacks power to crank the engine.

Possible "Vapor lock".

Check for engine codes.Possible bad temp sensor for ECU.

If fuel delivery is suspect ,try starting fluid into intake when "no start" occurs to diagnose fuel problem.

hot soak no cranks, nice post, clear as bell...
i bet it not heat. just lucky correlations.
the question is, does jumper starts , crank the engine fast, hot.(failed)
big time check that.
yes, then the battery is weak.
no, then the key line is dead.

see wiggle tricks here, works on all cars
with these, tricks, magic can happen, and the solution

Check the crank sensor wires as they may be oil soaked and not making contact.

Check the fuel pressure regulator for leaks, if that isn't it, it might be a leaking fuel injector.
