My Rendevous will sometimes not start. It seems to happen when I stop and try to start again fairly quickly (0-15 min). It will always start after waiting about 15-30 minutes.

Took to a mechanic shop and they said they couldn't reproduce it so nothing is wrong. I seem to be able to reproduce it regularly.

Any help is appreciated.

Do below don't wait for nothing something has to give here between fuel and spark and get back with me

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
