SpeckTater,

I had the EXACT same problem recently on my 1996 DT 115 Suzuki EFI.. It
started and ran just fine out to the lake.. Then all the sudden slowed
down and died.. I checked some things, pumped the bulb and wallah it
started again and took off.. 30 seconds later it died again. I just took
it into the shop. I will let you know what they tell me. Oh and I too
just had a 100 hour service done where they replace Water pumps and
clean fuel system, tune/ajust everything including the TPS.. And all of
that. So I am wondering if the mech that working on it screwed something
up. But it could be related to your issue... Dunno

I have a 1 year old 250 DT (two stroke). It started running rough just
before the 20 HR check up. The dealer adjusted the Throttle Position
Sensor (or throttle position valve)at that time and the engine ran
great for the next 50 hours.

The engine began to die at low (750 - 1000) RPM and would not start
untill the gas "bulb" was pumped up again.

At the 100 check the dealer found "debris" in the high pressure fuel
pump. However, they did not replace the fuel filter ? They also
adjusted the Throttle Position Sensor again. It runs smoothly at my
house. I have not had chance for all day fishig trip to test it.

My question, is anyone out there familiar to TPS (or throttle valve
sensor). The dealer claims it can be "adjusted" but only by the dealer.
In addition, they say that this is covered by warranty for only 30 days
after purchase ?

Any advise will be appreciated.
