Start engine run a min or more min it stall eng then turn off then turn on it fine ! all the time what cause ?
Have fuel pressure tested

get a circuit tester start it and check the battery to see what it is doing you should read 12.79 to 13.79 volts if it goes down to 9 or 10 volts and dies alternator!!! if it doesn't do the above I would look in to the coil pack!!
SOURCE: eng. dies just like you turn off swich starts backup runs great
Check the roll over protection switch. Make certain that the connection is good and not corroded.
RPM Northwest
SOURCE: runs fine for approx 15 mins,then stalls out and wont start again
sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.

It may be worthwhile to check the power lead from the ignition switch to the pcm. (may be a dark purple wire) If it has partial connection, it may take several turns of the key to "burn through" and make a decent electrical connection. This would not show up as a code otherwise it would set a code every time you started the vehicle. Same applies to external pcm ground leads. A poor connection often causes some heating at the connection point due to extra resistance there. After you turn it off, it can cool enough to again break the connection. Make sure that you check voltage at the wire behind the pin connector and again at the pin itself as many times the problem is where the pin joins the wire.
Could be wrong on this butr being here without the benefiot of "hands on" testing, it's my best guess.

chk and change complete throttle body with tps and idle motor also chk vaccum leaks
