2007 LTR450R FI

with map senor hooked to vacuum hose it only sparks twice at the spark plug. Unhook the vacuum hose and it sparks good. With hose connected engine will run 2 turns and stall. With hose unhooked it will start and idle but only take throttle one or 2 strong revs and start bogging out. Let idle for 4 seconds and it’ll rev again. Rev once and wait it’ll rev again and wait it keeps reving. When hose is hooked up it has trigger coil signal of 2 vac constantly and even when the sparks stops at the plug. I’ve done the fuel filter and pump filter and injector filter.and fpr check. And fuel pump inspection. And injector and map sensor and ecm. This is really getting old. Any guidance is appreciated. I haven’t messed with the tps? Any ideas?
