My Nissan Primastar van starts 1st time every morning but when the engine is warm/hot it does not want to start.

No year told or mileage on the car.
no engine told ok I will still try (my bad that)
the post is no good ,sorry
is the starter silent or not.???????
clicks only?
chatters badly, hopeless. both this
cranks fast and robustly, GRRRRGRRRRRR
I can not hear the car crank fast, nobody can.
see?
if stater motor fails top crank , make sure the battery lug ends all 4 ends are not lose or rusty if are fix that.
does car crank with jumper cable starts?
does the battery pass a load test
is battery rested, and 12.6vdc (or 10v bad)
if starter motor cranks engine robustly say so and we do 10 pages a wall of text on up to 25 tests with a tone of tools. and skills
1: fuses good is first (landing here)
2: scan the PCM when the engine fails
3c: check for spark
4:: if spark is good we check for no fuel injected or too much.
and now the wall of text (ok blocked by arthritis, )
