my hotpoint dryer was taking longer than normal to dry a load two to three times as long until no heat have pulled it apart checked duct all clean checked thermostats and safety all have continuity also checked the resistor, pulled the drum checked heating element in good shape put it all back together and heat worked for about 30 seconds and stopped rechecked it again all appears to be ok but dont have heat drum and blower both spinning properly, anybody have any thoughts or ideas it would be very helpfull i do have the wiring diagram

If everything has continyuity, did you check the voltage coming into the back of the dryer. Just because the dryer runs, does not mean that all the voltage is coming to the dryer. Tom ApplianceEducator.com

yes i have checked the voltage and is correct i also removed the timer and checked that all contacts have continuity at correct locations i am at a loss for ideas any more would be helpfull
the only temp selector is part of the timer wich i already checked and it is ok. i checked the motor switch and it is sending power to the element and i have heat but it comes and goes intermitently not sure why but every time the heat cuts off by the time i check it its all working again could this possibly be one of the sensors going bad?

If I were to take my guess, it would be the high limit thermostat, mounted on top of the heater housing. I had one do that to me. What I did was run the dryer, and soon as the heat stopped, i unplugged the dryer, and checked for continuity, at the thermostat, and did not get any. Check it out.

I do not remember who it was but there was a tech who was checking thermostat by putting them in an oven and then heating them up to different temperatures to see where they opened.
Just a thought.
If the thermostats are OK you may want to check the heating element again.
When you checked your element did you remove both wires and check not only for continuity but also to the case (should be infinite resitance).
Sometimes an element can ground out and if it is in just the right spot you get an overheated area if this is by thermostat it will open the thermostat.
Also they can ground out when hot due to the coil sagging.
Well its a good thing you replaced the thermostat, and did not stick it in the oven, and burn your self. LOL!!! Good Job!!! Tom http://www.applianceeducator.com
